Recommended Input Requirements
Over recommended operating supply and temperature ranges unless otherwise specified. (Note 2)
Switching Characteristics
Over recommended operating supply and temperature ranges unless otherwise specified. (Note 2)
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 device
should be operated at these limits. The tables of “Electrical Characteristics” specify conditions for device operation.
Note 2: Typical values are given for V
Note 3: LLHT and LHLT are measurements of transmitter LVDS data outputs rise and fall time over the recommended frequency range. The limits are based on
bench characterization and Guaranteed By Design (GBD) using statistical analysis.
Note 4: TPPOS is a measure of transmitter output pulse position in comparison with the ideal pulse position over the recommended frequency range. The limits are
based on bench characterization and Guaranteed By Design (GBD) using statistical analysis.
Note 5: TSTC and THTC are measurements of transmitter data inputs setup and hold time with clock input, CLKIN. The limits are based on bench characterization
and Guaranteed By Design (GBD) using statistical analysis.
Note 6: 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
without DC-Balance. The typical data is measured with a cycle-to-cycle jitter of
