Table 2. Transceiver Module Pad Description

Symbol

Functional Description

Din Ch 0 - 3 +/-

through

Transmitter diﬀerential data inputs for channels 0 through 3: Data inputs are CML compatible.

Din Ch 0 - 3 +/-

TX_DIS

Transmitter Disable: LVCMOS Input (Internal pull down). Control input used to turn oﬀ the

transmitter optical outputs. High Active. VCSEL array is oﬀ when High. Normal operation is

enabled when Low.

TX_EN

Transmitter Enable: LVCMOS Input (Internal pull up). Control input used to enable the trans-

mitter optical outputs. High Active. VCSEL array is oﬀ when Low. Normal operation is enabled

when High.

TX_FAULT*

Transmitter Fault: LVCMOS Output. Transmitter status output indicating an eye-safety over-cur-

rent condition for any VCSEL, an out of temperature range condition and/or a calibration data

corruption detection. High output state indicates normal operation. Low output state indicates

the fault condition. An asserted FAULT* condition disables the VCSEL array and is cleared by

TX_RESET*.

TX_RESET*

Transmitter Reset: LVCMOS Input (Internal pull up). Control input used to reset the transmitter

logic functions. Active Low. VCSEL array is oﬀ when Low. Normal operation is enabled when

High.

V_EE_TX

V_CC_TX

Transmitter signal common. All transmitter voltages are referenced to this potential unless oth-

erwise stated. Directly connect these pads to the PC board transmitter ground plane.

Transmitter power supply.

Dout Ch 0 - 3 +/-

through

Receiver diﬀerential data outputs for channels 0 through 3: Data outputs are CML compatible.

Data outputs are squelched for de-asserted Signal Detect.

Dout Ch 0 - 3 +/-

Receiver Signal Detect: LVCMOS Output. Receiver status output indicating valid signal in all

channels. High output state (asserted) indicates valid optical inputs to each and every channel.

Low output state (de-asserted) indicates loss of signal at any of the monitored receiver inputs.

All channels are monitored.

DNC

Do NOT Connect. Do not connect to any electrical potential.

V_EE_RX

Receiver signal common. All receiver voltages are referenced to this potential unless otherwise

stated. Directly connect these pads to the PC board receiver ground plane.

V_CCA_RX

V_CCB_RX

Pin preampliﬁer power supply rail.

Receiver quantizer power supply rail.

V_CCA_RX and V_CCB_RX can be connected to the same power supply. However, to insure maximum receiver sensitivity and

minimize the impact of noise from the power supply, it is recommended to keep the power supplies separate and to use the

recommended power supply ﬁltering network on V_CCA_RX (see Figure 8).

Module Case

Transceiver Case Common. Transceiver Case Common incorporates all exposed conductive sur-

faces and is electrically isolated from Transmitter Signal Common and Receiver Signal Common.
