... The CSPT855 is also able to track spread spectrum clocking for reduced EMI. Since the CSPT855 is based on PLL circuitry, it requires a stabilization time to achieve phase-lock of the PLL. This stabilization time is required following power up. POWERDOWN AND TEST LOGIC PLL 1 IDTCSPT855 , Y ) and one differential pair of feedback clock outputs [0: ...
