Introduction

The RPT-82/83 are integrated circuits that perform the active functions required for regenerative PCM repeaters. They can operate from less than 100kHz to greater than 3MHz. In PCM systems, information is transmitted by the presence or absence of bipolar pulses in specified time slots. The RPT-82/83 repeaters automatically adjust gain to optimize signal levels, determine if a pulse is present or not, and retransmit the reconstructed pulses. The difference between the RPT-82 and the RPT-83 is that the RPT-83 contains a clock-shutdown circuit. This shutdown circuit senses the incoming signal level and disables the clock drive if the incoming signal is below the level where accurate reconstruction is possible. This prevents noise or cross-talk from appearing as a valid signal that would be retransmitted.
