ZL50018
2 K Digital Switch with Enhanced
Stratum 3 DPLL
Data Sheet
Features
•
2048 channel x 2048 channel non-blocking digital
Time Division Multiplex (TDM) switch at 8.192
and 16.384 Mbps or using a combination of ports
running at 2.048, 4.096, 8.192 and/or
16.384 Mbps
32 serial TDM input, 32 serial TDM output
streams
Integrated Digital Phase-Locked Loop (DPLL)
exceeds Telcordia GR-1244-CORE Stratum 3
specifications
Output clocks have less than 1 ns of jitter (except
for the 1.544 MHz output)
DPLL provides holdover, freerun and jitter
attenuation features with four independent
reference source inputs
Programmable key DPLL parameters (filter
corner frequency, locking range, auto-holdover
