CHAPTER 1
INTRODUCTION
1 .l GENERAL
The CTM-05 is a multi-function counter-timer and digital expansion board for the IBM PC and
compatibles. The board offers five I&bit up/down counters, a IMHz crystal timebase with divider,
and separate general-purpose g-bit TTL input/output (I/O) ports. An Advanced Micro Devices
AMD-9513 System Timing Controller IC (Integrated Circuit) supports the board's counting and timing
functions.
1.2 FEATURES
l Five independent l&bit up/down counters.
l 7 MHz maximum input frequency.
l Binary or BCD counting.
l 1 MHz internal crystal oscillator with tapped scaler.
l Programmable frequency output.
l Time-Of-Day option.
l Alarm comparators on Counters 1 and 2.
l Complex-duty-cycle outposts.
l One-shot or continuous outputs.
l Programmable count gate/source selection.
l Programmable input and output polarities.
l Programmable gate functions.
Additional functions separate from the counter-timer include the following:
l Eight bits of lTL/DTL digital input with latch.
- Eight bits of TTL/DTL digital output with latch.
l Level-selectable interrupt input channel.
1.3 APPLICATIONS
l Event counting for pulse-output devices (flowmeters, wattmeters, etc.).
l Programmed frequency synthesis.
l Co-incidence alarms.

l Frequency measurements.
l F/V conversion and pulse accumulation.
9 Period and pulse duration measurements.
l Time dealy generation.
l Periodic interrupt generation.
l Frequency Shift Keying @SK).

1.5 OPTIONAL I/O ACCESSORIES
To simplify complex I/O connections, an optional screw-connector board (STA-U) connects to the
CTM-05 Board I/O connector via a flat-insulation displacement cable (C-1800).
