Reset

CMOS input. Assert “Reset” high at the end of previous burst, 2 bytes in duration

2

Pmon_analog

Analog signal output for receiver optical input power monitoring

3

RX_GND

Rx Ground

4

11

TX_Vcc

Tx Vcc

12

TX_GND

Tx Ground

13

TX_DIS

Tx Disable. LVTTL input. Laser output is disabled when this pin is asserted high or left

unconnected. Laser output is enabled when this pin is asserted low.

14

TXD+

Positive Data Input, LVPECL or CML (AC coupled; internally 100 ohms differential termi-

nation)

15

Negative Data Input, LVPECLor CML (AC coupled; internally 100 ohms differential termi-

nation)

16

TX_GND

Tx Ground

17

SCL

2-Wire Serial Clock Input. Clocks data into and out of the device.

18

SDA

2-Wire Serial Data I/O Pin. Transfers serial data to and from the device.

19
