File name Tda4691.pdf INTEGRATED CIRCUITS DATA SHEET TDA4691 Sync Processor with Clock (SPC) Preliminary specification File under Integrated Circuits, IC02 September 1993 Philips Semiconductors Preliminary specification Sync Processor with Clock (SPC) FEATURES · Sync processor for horizontal (H) and vertical (V) sync pulses generated by internal 13.5 MHz oscillator · Stable `On Screen Display (OSD)', if no input signal is present with free running internal oscillator; automatic turn over to locked oscillator, if input signal is available · External clock oscillator can be used · Standard 50/60 Hz signals are identified automatically · Additional outputs for 13.5 MHz, composite sync, 50//60 Hz identification, signal identification (mute), super-sandcastle 12 V · TTL compatible outputs (H, V, composite sync and 13.5 MHz) · 3 different time constants for the PHI1 PLL: fast, normal and slow (T1, T2 and T3). Fast and normal time constant are set independent from each other · Start of H-pulse definable by application · Digital interference reduction for H and V signals · Digital noise detector · Time correction of non-standard H-pulses and equalizing pulses for optimum PLL control. GENERAL DESCRIPTION The TDA4691 is a bipolar integrated circuit for sync processing in 50/100 and 60/120 Hz TV sets, preferably in conjunction with the programmable deflection controller TDA9150. A line locked 13.5 MHz clock with several dividers and logic circuitry is available generating the horizontal and vertical sync outputs. The device can be assembled in a DIL20 or SO20 package.
