•

32 serial TDM input, 32 serial TDM output

streams

*Pb Free Matte Tin

**Pb Free Tin/Silver/Copper

Integrated Digital Phase-Locked Loop (DPLL)

exceeds Telcordia GR-1244-CORE Stratum 3

specifications

-40°C to +85°C

•

Programmable key DPLL parameters (filter corner

frequency, locking range, auto-holdover

hysteresis range, phase slope, lock detector

range)

•

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)

Output streams can be configured as bi-

directional for connection to backplanes
