Electrical Characteristics
Basic functionality and specifications per deserializer channel will be similar to National Semiconductor’s DS92LV1212A.
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 Vcc = 3.3V and TA =25˚C
Note 3: Current into the device pins is defined as positive. Current out of device pins is defined as negative. Voltage are referenced to ground except VTH and VTL
which are differential voltages.
Note 4: Only one output should be shorted at a time. Do not exceed maximum package power dissipation capacity.
Note 5: For the purpose of specifying deserializer PLL performance t
the incoming data stream (SYNCPATs). t
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). The time to lock to random data is dependent upon the incoming data.
Note 6: t
Margin is Guaranteed By Design (GBD) using statistical analysis.
Note 7: Because the Bus LVDS serial data stream is not decoded, the maximum frequency of the CHTST output driver could be exceeded if the data stream were
switched to CHTST. The maximum frequency of the BUS LVDS input should not exceed the parallel clock rate.

Deserializer Noise Margin
is a measure of how much phase noise (jitter)the deserializer can tolerate in the incoming data stream before bit errors occur. The Deserializer Noise
Parameter
DSR1
is the time required for the deserializer to indicate lock upon power-up or when leaving the power-down mode. t
