2.488Gbps 1:4 Demultiplexer with Clock and
Data Recovery and Limiting Amplifier
AC ELECTRICAL CHARACTERISTICS (continued)
(V
Note 3: AC characteristics are guaranteed by design and characterization.
Note 4: Jitter tolerance is guaranteed (BER ≤ 10
Note 5: Measured with the input amplitude set at 100mV
Note 6: Measured with 10mV
Note 7: Measured at OC-48 data rate using a 0.068µF loop-filter capacitor.
Note 8: Under LOL condition, the CDR clock output is set by the external reference clock.
Note 9: Relative to the falling edge of PCLK+. See Figure 3.
