Definition
Tx Fail Alarm. LVTTL Output Active High
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.
2-Wire Serial Data I/O Pin.
2-Wire Serial Clock Input.
Internally Grounded
CMOS input. Assert “Reset” high at the end of previous burst, 2 bytes in duration
LVTTL output. BRST_Det assert low when module receives “reset” signal, assert high
when incoming burst is present.
RSSI acquire/hold LVTTL Input. Digital RSSI output through I2C
