Functional Description
VEE
Transmitter Signal Common. All voltages are referenced to this potential unless otherwise indicated. Directly
connect these pads to transmitter signal ground plane.
VCCT
Transmitter Power Supply. Use recommended power supply filter circuit in Figure 6.
DIN0+ through DIN11+
Transmitter Data In+ for channels 0 through 11, respectively. Differential termination and self bias are included,
see Figure 11.
DIN0– through DIN11–
Transmitter Data In- for channels 0 through 11, respectively. Differential termination and self bias are included;
see Figure 11.
TX_EN
TX Enable. Active high. Internal pull-up High = VCSEL array is enabled if TX_DIS is inactive (Low). Low =
VCSEL array is off. TX_EN must be taken to a logic low state level (VOL) for 1 ms or longer.
TX_DIS
TX Disable. Active high. Internal pull-down Low = VCSEL array is enabled if TX_EN is active (High). High =
VCSEL array is off. TX_DIS must be taken to a logic High state level (VOH) for 1 ms or longer.
RESET-
Transmitter RESET- input. Active low. Internal pull-up. Low = Resets logic functions, clears FAULT- signal,
VCSEL array is off. High = Normal operation. See Figure 14.
FAULT-
Transmitter FAULT- output. Active low. Low (logic "0") results from a VCSEL over-current condition, out of
temperature range, or EEPROM calibration data corruption condition detected for any VCSEL. An asserted (logic
"0") FAULT- disables the VCSEL array and is cleared by RESET- or power cycling VCCT FAULT- is a single ended
LVTTL compatible output.
DNC
Do not connect to any electrical potential.

Functional Description
VEE
Receiver Signal Common. All voltages are referenced to this potential unless otherwise indicated.
Directly connect these pads to receiver signal ground plane.
VCCR
Receiver Power Supply. Use recommended power supply filter circuit in Figure 5.
VPP
Not required for Avago Technologies product. Pads not internally connected.
(Voltage for MSA compatibility in order to ac-couple receiver data outputs).
DOUT0+ through DOUT11+
Receiver Data Out+ for channels 0 through 11, respectively. Terminate these high-speed differential CML outputs
with standard CML techniques at the inputs of the receiving device. Individual data outputs will be squelched for
insufficient input signal level.
DOUT0– through DOUT11–
Receiver Data Out- for channel 0 through 11, respectively. Terminate these high-speed differential CML outputs
with standard CML techniques at the inputs of the receiving device. Individual data outputs will be squelched for
insufficient input signal level.
SD
Signal Detect. Normal optical input levels to all channels results in a logic "1" output, VOH, asserted. Low input
optical levels to any channel results in a fault condition indicated by a logic "0" output, VOL, de-asserted. SD is a
single-ended LVTTL compatible output.
RX_EN
Receiver output enable. Active high (logic "1"), internal pull-up. Low (logic "0") = receiver outputs disabled, all
outputs are high (logic "1").
SQ_EN
Squelch enable input. Active high (logic "1"), internal pull-up. Low (logic "0") = squelch disabled.
When SQ_EN is high and SD is low, corresponding outputs are squelched.
EN_SD
Enable Signal Detect. Active high (logic "1"), internal pull-up. Low (logic "0") = Signal detect output forced
active high.
DNC
Do not connect to any electrical potential.
