Power-Supply Connection for Input. Connect to +3.3V.
Positive Data Input, CML. This input is internally terminated with 50 to V
Negative Data Input, CML. This input is internally terminated with 50 to V
Circuit Ground
Output-Swing Control Input, LVTTL with 40k Internal Pullup. Set to TTL high or open for maximum
output swing, or set to TTL low for reduced swing.
Output Preemphasis Control Input, LVTTL with 10k Internal Pullup. This pin is the most significant bit
of the 2-bit preemphasis control. Set high or open to assert this bit.
Output Preemphasis Control Input, LVTTL with 10k Internal Pullup. This pin is the least significant bit
of the 2-bit preemphasis control. Set high or open to assert this bit.
Negative Data Output, CML. This output is terminated with 50 to V
Positive Data Output, CML. This output is terminated with 50 to V
Power-Supply Connection for Output. Connect to +3.3V.
Transmitter Disable Input, LVTTL with 10k Internal Pullup. When high or open, differential output is
40mV
Loss-of-Signal Detect, TTL Output. This output is open-collector TTL, and therefore requires an external
4.7k to 10k pullup resistor (5.5V maximum). This output sinks current when the input signal level is
valid.
LOS Sensitivity Control Input, LVTTL with 40k Internal Pullup. Set to TTL high or open for less
sensitivity (higher assert threshold). Set to TTL low for more sensitivity (lower assert threshold).
Exposed Pad. For optimal thermal conductivity, this pad must be soldered to the circuit board ground.
