• RBS1/0 = 00: two frame buffer or 386 bits
• RBS1/0 = 01: one frame buffer or 193 bits
• RBS1/0 = 10: short buffer or 96 bits
• RBS1/0 = 11: Bypass of the receive elastic buffer
The functions are:
• Clock adaption between system clock (SCLKR) and internally generated route clock
• Compensation of input wander and jitter.
• Frame alignment between system frame and receive route frame
• Reporting and controlling of slips
Controlled by special signals generated by the receiver, the unipolar bit stream is
converted into bit-parallel, time slot serial data which is circularly written to the elastic
buffer using internally generated Receive Route Clock (RCLK).
Reading of stored data is controlled by the system clock sourced by SCLKR or by the
receive jitter attenuator and the synchronization pulse (SYPR) together with the
programmed offset values for the receive time slot/clock slot counters. After conversion
into a serial data stream, the data is sent out on port RDO. If the receive buffer is
bypassed programming of the time slot offset is disabled and data is clocked off with
RCLK instead of SCLKR.
