ClockLock & ClockBoost Timing Parameters
For the ClockLock and ClockBoost circuitry to function properly, the
incoming clock must meet certain requirements. If these specifications are
not met, the circuitry may not lock onto the incoming clock, which
generates an erroneous clock within the device. The clock generated by
the ClockLock and ClockBoost circuitry must also meet certain
specifications. If the incoming clock meets these requirements during
configuration, the ClockLock and ClockBoost circuitry will lock onto the
clock during configuration. The circuit will be ready for use immediately
after configuration.
