2.13.2 PLL Lock detect counters
These 4 bit counters count the consecutive comparison cycles where the lock detect circuit gives an in-lock result.
When the counter reaches its programmed count then that PLL is deemed to have achieved full lock. This prevents
spurious false in-lock signals while the PLL is achieving lock up. There are separate counters for the UHF, Rx VHF
and Tx VHF PLLs which are programmed as shown above. Bits 15,11,7 are the MSB's for the UHF, Rx VHF and Tx
VHF PLL lock detector counters respectively. A non zero value must be programmed for the lock detect to operate
correctly.
3.0 Absolute Maximum Ratings
This device is sensitive to ESD. Most pins have an ESD rating greater than 2000 V (Human Body Model HBM),
however some pins have limited protection (800 to 2000 V) in order to meet the RF performance requirements.
Anti-static precautions should be used when handling this device.
