Description of Operation
1. Clock and data recovery
The PLL in the clock and data recovery block must be frequency locked to the external REFCLK before locking
to the data.
The LKREFN pin is used to lock the frequency. When the LKREFN pin is low, the PLL frequency is locked to
the external REFCLK and when high, it is locked to the input serial data. Up to 800μs is required to lock the
frequency.
2. Frequency detector
The frequency detector constantly monitors the offset between the clock obtained by 1/20 frequency-dividing
the recovered clock and the external REFCLK. It outputs high when this offset is less than 1.6%, and low when
this offset is 1.6% or more.
Note on Operation
The following values are recommended for the external resistors and capacitor used as the loop filter.
