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
CC
= 3.3V and T
A
= +25C.
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:
t
LLHT
and t
LHLT
specifications are Guaranteed By Design (GBD) using statistical analysis.
Note 5:
Because the Serializer is in TRI-STATE mode, the Deserializer will lose PLL lock and have to resynchronize before data transfer.
Note 6:
t
DJIT
specifications are Guaranteed By Design using statistical analysis.
Note 7:
For the purpose of specifying deserializer PLL performance, tDSR1 and tDSR2 are specified with the REFCLK running and stable, and with specific
conditions for the incoming data stream (SYNCPATs). It is recommended that the derserializer be initialized using either t
DSR1
timing or t
DSR2
timing. t
DSR1
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. t
DSR2
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 8:
t
RNM
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
Margin is Guaranteed By Design (GBD) using statistical analysis.
