• Manufacturer: Integrated Device Technology

DC ELECTRICAL CHARACTERISTICS OVER OPERATING RANGE
Following Conditions Apply Unless Otherwise Specified:
Commercial: T
NOTES:
1. All typical values are at respective nominal V
2. Differential cross-point voltage is expected to track variation of V
TIMING REQUIREMENTS
NOTES:
1. Recovery time required when the device goes from power-down mode into bypass mode (test mode with AV
2. Time required for the integrated PLL circuit to obtain phase lock of its feedback signal to its reference signal. For phase lock to be obtained, a fixed-frequency, fixed-phase reference

signal must be present at CLK. Until phase lock is obtained, the specifications for propagation delay, skew, and jitter parameters given in the switching characteristics table are
not applicable. This parameter does not apply for input modulation under SSC application.
