IDTCSPT855 Integrated Device Technology, IDTCSPT855 Datasheet - Page 3

• Manufacturer Part Number: IDTCSPT855
• Description: 2.5v Phase Locked Loop Clock Driver
• Manufacturer: Integrated Device Technology

FUNCTION TABLE
NOTES:
1. H = HIGH Voltage Level
2. Typically 10MHz.
RECOMMENDED OPERATING CONDITIONS
NOTES:
1. Unused inputs must be held HIGH or LOW to prevent them from floating.
2. DC input signal voltage specifies the allowable DC execution of differential input.
3. Differential input signal voltage specifies the differential voltage | V
4. Differential cross-point voltage is expected to track variations of V
