Applications

•

Synchronizer for POTS line cards

Rate convert NTR 8kHz or GPON physical

interface clock to TDM clock

Description

The ZL30111 POTS line card PLL contains a digital

phase-locked loop (DPLL), which provides timing and

synchronization for SLIC/CODEC devices.

The ZL30111 generates TDM clock and framing

signals that are phase locked to the input reference.

It helps ensure system reliability by monitoring its

reference for stability and by maintaining stable

output clocks during short periods when the

reference is unavailable.
