ZL30110
Telecom Rate Conversion DPLL
Features
• Synchronizes to 8 kHz, 2.048 MHz, 8.192 MHz or
16.384 MHz
• Provides a range of output clocks:
• 65.536 MHz TDM clock locked to the input
reference
• General purpose 25 MHz fan-out to 6 outputs
locked to the external crystal or oscillator
• General purpose 125 MHz and 66 MHz or
100 MHz locked to the external crystal or
oscillator
• Provides DPLL lock and reference fail indication
• Automatic free run mode on reference fail
• DPLL bandwidth of 922 Hz for all rates of input
reference and 58 Hz for an 8 kHz input reference
• Less than 5 psecrms on 25 MHz outputs, and less
than 0.6 nspp intrinsic jitter on the all other outputs
• Minimal input to output and output to output skew
• 25 MHz external master clock source: clock
oscillator or crystal
• Simple hardware control interface

Description
The ZL30110 clock rate conversion digital phase-
locked loop (DPLL) provides accurate and reliable
frequency conversion.
The ZL30110 generates a range of clocks that are
either locked to the input reference or locked to the
external crystal or oscillator.
In the locked mode, the reference input is continuously
monitored for a failure condition. In the event of a
failure, the DPLL continues to provide a stable free
running clock ensuring system reliability.
