ZL50015
Enhanced 1 K Digital Switch with
Stratum 4E DPLL
Data Sheet
Features
•
1024 channel x 1024 channel non-blocking digital
Time Division Multiplex (TDM) switch at 4.096,
8.192 and 16.384 Mbps or using a combination of
ports running at 2.048, 4.096, 8.192 and
16.384 Mbps
16 serial TDM input, 16 serial TDM output
streams
Integrated Digital Phase-Locked Loop (DPLL)
exceeds Telcordia GR-1244-CORE Stratum 4E
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
Exceptional input clock cycle to cycle variation
tolerance (20 ns for all rates)
