Applications
• Synchronizer for POTS SLIC/CODEC
• Rate convert NTR 8 kHz or GPON physical
interface clock to TDM clock
Description
The ZL30112 SLIC/CODEC DPLL contains a digital
phase-locked loop (DPLL), which provides timing and
synchronization for SLIC/CODEC devices.
The ZL30112 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.
