ZL50022
Enhanced 4 K Digital Switch with
Stratum 4E DPLL
Data Sheet
Features
• 4096 channel x 4096 channel non-blocking digital
Time Division Multiplex (TDM) switch at
8.192 Mbps and 16.384 Mbps or using a
combination of ports running at 2.048, 4.096,
8.192 and 16.384 Mbps
• 32 serial TDM input, 32 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
