General Description

The 8400110 is a Low Jitter Telecom Rate-Conversion PLL that

provides accurate and reliable frequency conversion.

The 8400110 generates a 65.536MHz clock that is 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 PLL continues to

provide a stable free-running clock, ensuring system reliability.

Features

• One 65.536MHz output, synchronized to 8kHz reference

• One 25MHz output, buffered version of the internal osc output

• Provides lock and reference fail indication

• Free run mode when reference clock (REF) fails

• Automatic switch-over to reference when good reference (REF) is

available

• 25MHz external master clock source: crystal or oscillator

• Full 3.3V operation

• -40°C to 85°C ambient operating temperature

• Available in a lead-free (RoHS 6) package
