VEEE
VCCE – 1.3V
Serial ECL data input.
When TXSER is high,
this input signal is
output from SDOUT.

VCCE – 1.3V
Lost-of-light signal
input.
Low level when this
pin is left open.

high level
TTL-IN
Test pin.

TTL level
TTL-IN
VEET
VEEG
Loop-back enable.
If LPBK is set to high,
the signal output from
SDOUT when LPBK
is low is transmitted to
the RX input with the
internal connection.
In this time, SDOUT/
SDOUT∗ are fixed to
VEEG
low/high respectively
and SDIN/SDIN∗ are
both disabled.
