Receiver Switching Characteristics
Over recommended operating supply and temperature ranges unless otherwise specified.
Note 4: The Minimum and Maximum Limits are based on statistical analysis of the device performance over voltage and temperature ranges. This parameter is
functionally tested on Automatic Test Equipment (ATE). ATE is limited to 85MHz. A sample of characterization parts have been bench tested at 112MHz to verify
functional performance.
Note 5: The limits are based on bench characterization of the device’s jitter response over the power supply voltage range. Output clock jitter is measured with a
cycle-to-cycle jitter of
in the clock edge from most graphics VGA chips currently available. This parameter is used when calculating system margin as described in AN-1059.
Note 6: Receiver Skew Margin is defined as the valid data sampling region at the receiver inputs. This margin takes into account transmitter output pulse positions
(min and max) and the receiver input setup and hold time (internal data sampling window - RSPOS). This margin allows for LVDS interconnect skew, inter-symbol
interference (both dependent on type/length of cable) and clock jitter.
RSKM ≥ cable skew (type, length) + source clock jitter (cycle to cycle).
