IOUT
Transmit LED output. This open-
collector current output drives
NRZI waveforms into an LED.
Output current can be set
externally by choosing RTSET
value.

AV
1
Analog positive power supply
CC
44
TXC
Transmit clock TTL input. This
25MHz clock is phase-aligned
with the internal 125MHz TX bit
clock. Data appearing at
Tsm<4:0> are clocked into the
ML6695 on the rising edge of this
clock.

AGND2
Analog ground
AV 2
CC
Analog positive power supply
LPBK
Loopback TTL input pin. Tying this
pin to ground places the part in
loopback mode; data at TSM0 0-4
are serialized, then sent to the
quantizer, followed by the receive
PLL for clock recovery, and finally
to the RSM<4:07> outputs.
Floating this pin or tying it to V
CC
places the part in its normal mode
of operation.
