Now,
in their seventh generation, L-3 TW's bit synchronizers are
designed to provide high-speed bit and format synchronization
with flexible data processing, distribution, and display.
Our EMR 832 performs input signal conditioning, bit
synchronization, data reconstructions, code conversion,
clock generation, and output conditioning to provide
clean, synchronous serial data and clock signals.
It comes as a self-contained RETMA rack-mount chassis
that houses one to four bit synchronizers. Each
synchronizer may be set up from either the front panel
using the keypad and a large LCD display panel, or
remotely over an RS-232 interface in a format compatible
with the EMR 8320.
The EMR 832 provides a tunable bit
rate capability over its full operating range of 60
bps to 30 Mbps with data in any standard IRIG code
format as input. Outputs of clean serial NRZ-L
data and synchronous clocks are provided at the rear
panel of each bit synchronizer. The power and
remote control connectors are at the rear of
the chassis.

The MBS-740 PCM Bit Synchronizer is L-3’s eighth generation external PCM bit synchronizer. It is part of a family of high-performance PCM telemetry products we have designed to provide high-speed bit and format synchronization with flexible data processing, distribution, display, and remote configuration capabilities.
| Features |
- 3U rack-mount houses 1 to 4 PCM bit synchronizers
- Selects any center frequency to within 0.1% at 100 bps to 40 Mbps for NRZ codes and to 30 Mbps for bi-phase codes
- BER within 1.0 dB of theoretical over the entire operational range
- Second-order phase-locked loop extracts a stable clock from noisy and distorted input signals
- Provides fast acquisition of new signals and retention during temporary signal dropouts
- Automatic gain and offset controls track amplitude and offset variations and rapidly adapt to signal changes
