PC Board Transmitter Negative Data Outputs, CML. These outputs are terminated with 50
Ω to VCC4.
67
RX_PE
PC Board Transmitter Preemphasis Control Input, LVTTL with 40k
Ω Internal Pullup. Set high or open
to assert this bit.
68
LOOPBACK
Loopback Enable Input, LVTTL with 40k
Ω Internal Pullup. Set low for normal operation. Set high or
open for internal connection of TX_IN to RX_OUT. TX_OUT continues to transmit when loopback is
enabled.
EP
Exposed Pad
Exposed Pad. Signal and supply ground. For optimal high-frequency performance and thermal
conductivity, this pad must be soldered to the circuit board ground.
