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.
