Deserializer Switching Characteristics
Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The table of “Electrical Characteristics” specifies conditions of device operation.
Note 2: Typical values are given for V
Note 3: Current into device pins is defined as positive. Current out of device pins is defined as negative. Voltages are referenced to ground except VOD, VOD, VTH
and VTL which are differential voltages.
Note 4: For the purpose of specifying Deserializer PLL performance tDSR1 and tDSR2 are specified with the REFCLK running and stable, and specific conditions
of the incoming data stream (SYNCPATs). It is recommended that the Deserializer be initialized using either tDSR1 timing or tDSR2 timing. tDSR1 is the time required
for the Deserializer to indicate lock upon power-up or when leaving the power-down mode. Synchronization patterns should be sent to the device before initiating
either condition. tDSR2 is the time required to indicate lock for the powered-up and enabled Deserializer when the input (RI+ and RI-) conditions change from not
receiving data to receiving synchronization patterns (SYNCPATs).
Note 5: tRNM is a measure of how much phase noise (jitter) the Deserializer can tolerate in the incoming data stream before bit errors occur.
