CS61600 Datasheet, PDF (1/14 Pages) List of Unclassifed Manufacturers – PCM JITTER ATTENUATOR

Semiconductor Corporation
CS61600
PCM Jitter Attenuator
Features
General Description
• Unique Clock-Tracking Circuitry Filters
50 Hz or Higher Frequency Jitter for
T1 and PCM-30 Applications
• ^{Minimal External Components Required}
• ^{14 Pin DIP}
• ^{Single 5 Volt Supply}
• ^{3 Micron CMOS for High Reliability}
and Low Power Dissipation: 50 mW
Typical at 25 °C
The CS61600 from Crystal Semiconductor accepts T1
(1.544 Mb/s) or CCITT standard (2.048 Mb/s) data and
clock inputs, and tolerates at least 7 (and up to 14) unit
intervals, peak-to-peak, of jitter. Before outputting data
and clock, jitter is attenuated using an internal clock-
tracking variable oscillator and a 16 bit FIFO elastic
store.
The jitter attenuation function can be determined by
appropriate specification of the external crystal.
The CS61600 is transparent to data format, and is in-
tended for application in carrier systems, switching
systems, Local Area Network gateways and multiplex-
ers.
