• Manufacturer: Integrated Device Technology

Electrical Characteristics - DIF 0.7V Current Mode Differential Pair

Notes:
1.Guaranteed by design and characterization, not 100% tested in production.
2. All Long Term Accuracy and Clock Period specifications are guaranteed assuming that the input frequency meets CK410B accuracy requirements
3.IREF = VDD/(3xRR). For RR = 475Ω (1%), IREF = 2.32mA. IOH = 6 x IREF and VOH = 0.7V @ ZO=50Ω.
4. Measured into fixed 2 pF load cap. Input to output skew is measured at the first output edge following the corresponding input.
5. Measured from differential cross-point to differential cross-point
6. All Bypass Mode Input-to-Output specs refer to the timing between an input edge and the specific output edge created by it.
