Introduction
General
The PHF5 is a compact handsfree unit for handportable telephones and it provides a possibility to use HF operation. The phone cannot be used as a handset but the PHF5 can be upgraded with a handset and an antenna coupler. The hook off signal is given to the phone when a handset is lifted from the hook. The PHF5 has an internal speaker and external microphone.
Technical Summary
Operation
The PHF5 can be powered by LCH6 or LCM1 rapid chargers to provide rapid charging for the phone also during a HF call. The LCH8 tricle charger is not recommended for powering the PHF5 because during a HF call there will be insufficient charging current available for the phone. The phone is connected to the unit by a system connector. The cable length including the connector housing is 15 cm. The other connectors are d.c. jack (input from the charger), microphone connector and a handset connector. There is no RF connector or external speaker connector in the PHF5. The PHF5 has an internal HFspeaker.

Modes of Operation
Power Off The module does not receive supply voltage from a charger to the d.c. connector. There are no voltages on the module. Power on/Mute on The d.c. voltage in the XEAR line is below 0.5 V. There is no audio input signal present. HF speaker amplifier and headset amplifier are muted. The current consumption is below 10 mA. Power on/Mute off The d.c. voltage in the XEAR line is above 1 V. If there is no handset connected or the handset is on hook, the XEAR signal is routed to the HF speaker and the HF microphone signal is routed to the XMIC line. If the handset is off hook, the XEAR signal is routed to the handset speaker and the handset microphone signal is passed to the XMIC line.
Modes of Audio Output Destination and Hook
The audio output is routed to handset connector if a handset is connected and it is lifted from the cradle a headset is connected a button headset is connected Otherwise the audio output is routed to the internal speaker and HF microphone signal is routed to XMIC. The hook off signal is passed to the phone if audio output is routed to external device. This means that whether a normal or a button headset is connected, the hook is also always off.
Switching Delay between Handset Mode to/from HF Mode
The internal logic for audio routing and hook signal includes a delay, which is to prevent erroneous behaviour of the whole system when switching between modes. The hook signal for phone is given without any delay. The audio routing is delayed for about 0.5 seconds, when the audio routing is to change from handset mode to HF mode. The delay is below 100 milliseconds, when the audio routing is to change from HF mode to handset mode.

Circuit Description
The circuit blocks are described in these subsections. Refer to block diagram.
Connectors
There are 4 connectors to other units, and internal speaker connector. There are d.c. input, phone bottom connector, microphone and handset/headset connector. The incoming d.c. voltage is routed directly to system connector VCC pin.
Input Protection
The purpose of the input protection is to prevent ESD, RF and high or negative input voltages to damage the module. Contacts that are subject to ESD are protected with diode pairs. All inputs (as well as test pads) are protected from RF. The RF shield metal plate (assembly part) is the physical interface subject to RF shielding.

CAP interface
This block converts signal levels and also provides singleended to differential and level conversions as well as hook pulldown and device identification.
Audio In
The circuit performs differential to singleended conversion of incoming audio signal. The function is: EAR = SGNDXEAR (Gain is 0 dB). Output d.c. bias in EAR line is 2 V, input is a.c. coupled, and the stage tolerates about ±1.5 V combined common mode + differential mode input swing without clipping.
Audio Out
The circuit performs sum operation with minimum phase shift. The function is: XMIC = SGNDMIC (Gain is 0 dB). Input d.c. bias in MIC line must be 2 V, output d.c. is not affected. The stage tolerates about ±1.5 V combined SGND and MIC line swing without clipping.
Device Identification
There is a 22 k d.c. identification resistor connected from XMIC line to GND.
Hook
The circuit pulls HOOK line down when HOOKOFF line is high. The function is: HOOK = HOOKOFF. There is no pullup in the module.
5 V Regulation
The charger voltage is used as the input voltage for the module, and this block regulates it to 5 V (named +5V in schematic). For low charger voltage input, the maximum drop is 0.5 V so the block is full operative for input voltages downto 5.5 V.
2 V and 4 V Regulation
This block reregulates the 5 V voltage to high ripple rejection 4 V line (named VSTAB in schematic) and further to 2 V (named +2V in schematic). +2 V is used as half voltage for audio stages and VSTAB is used for microphone biasing and low level microphone amplifier supply voltage.
Speaker Amplifier
This block is s.c. coupled full bridge speaker output stage. It has own 2.4 V half voltage which is seen at both outputs SP+ and SP. The output swing is 3 VRMS and expected load is 15 ohms. It is possible to use a 8 speaker, too,

but this doubles the power consumption and temperature rise of the IC and therefore it might reduce lifetime. The amplifier is on when HFMUTE is off (below 2.4 V).
Headset Capsule Amplifier
This block is a current booster block that doubles the EAR input voltage but has significant output impedance together with input protection block (100 ). The load of the handset is also 100 , so the actual gain is 0 dB for handset. A headset with 32 load impedance gets therefore less power, and the gain is 6 dB. This matches the amplifier output for either device plugged in the handset connector. Maximum output voltages are 550 mVRMS for handset and 225 mVRMS for headset, seen at the handset connector with 110 and 32 loads, respectively. The amplifier is on when HSMUTE is about 5 % below the +2 V line level. The amplifier is off when HSMUTE is below 0.7 V. Levels between these are forbidden (except level transients) and lead to distorted output.
HF Microphone Preamplifier
This block is used for high performance preamplifying of the HF microphone signal. The mic is biased from VSTAB in this block. VSTAB is also used as a supply voltage for the amplifier. The block is used also for level matching between the two mic inputs, as they have common amplifier/selector stage (Microphone amplifier). The gain is 10 dB, input impedance is 2 k. The output d.c. voltage is around 0.6 V, but when tied to GND by microphone amplifier block, the amplifier is disabled.
Handset Microphone Preamplifier
This block is used for high performance preamplifying of the handset microphone signal. The mic is biased from VSTAB in this block. VSTAB is also used as a supply voltage for the amplifier. The block is used also for a.c. level matching between the two mic inputs, as they have common amplifier/selector stage (Microphone amplifier). The gain is 17 dB, input impedance is 2 k. The output d.c. voltage is around 0.6 V.
Microphone Amplifier
This block is used as a microphone selector and is also postamplifies the signal providing the low output impedance MIC signal for the CAP interface block. The two mic inputs are a.c. coupled and the output (MIC line) is biased to 2 V. The EXTAUD line is used for input selection. When the EXTAUD is high, the HF microphone line is tied to GND, which disables the whole HF microphone preamplifier block increasing rejection in handset mode. When the EXTAUD is low, the handset microphone amplifier block is operative but it cannot have any signal. The gain in this stage is 20 dB for both of the input signals.

Hookoff Sense
This block monitors the handset microphone current and provides HOOKOFF and EXTAUD signals. The current of the 2.2 k bias resistor of the handset microphone preamplifier block is monitored (by monitoring voltage drop) and if the d.c. resistance of the handset microphone is less than about 50 k, the HOOKOFF line is tied high (above 3 V), othervise low (below 0.1 V). The EXTAUD line is following the HOOKOFF line, with RC time constant of 470 milliseconds. The 50 k d.c. impedance in the handset microphone corresponds to about 80 mA. If a handsfree microphone is plugged to handset plug, the block will identify this as a handset or headset, and the audio output is shorted by the mono plug of the HF microphone.
Muting Logic
This block monitors the XEARP and EXTAUD lines, and gives the HFMUTE and HSMUTE signals, that switch the speaker and handset capsule amplifiers to correct modes. This block is extremely levelsensitive and it does not have simple "0" or "1" input or output signals. The XEARP d.c. level is monitored, and if the d.c. is below 0.7 V, both outputs will be in mute state regardless of the EXTAUD state. If the XEARP d.c. is above 0.7 V, the circuit creates internal reference level of 0.5 V, and decision is made using the EXTAUD signal; if EXTAUD is above 0.5 V, the HSMUTE will be off, and HFMUTE will be on. If XEARP d.c. level is above 0.6 V and EXTAUD is below 0.5 V, then HFMUTE will be off and HSMUTE will be on. The HFMUTE signal onlevel is above 3 V and offlevel is below 0.7 V (When HFMUTE is on, the speaker amplifier is in shutdown). The HSMUTE signal onlevel is below 0.1 V and offlevel is 5 % below +2 V line level. There is a RC time constant of 0.1 seconds when changing between these levels.
