TXSQLCH
I
LVTTL
Transmit Data Squelch.
When TXSQLCH is set low, the output data stream on
TXDOUT is forced to a zero state. Set TXSQLCH high
for normal operation. The TXSQLCH input is ignored
when operating in Line Loopback mode (LLBK = 0).
Note: This input has an internal pullup.

VDDIO
1.8 V or 3.3 V LVTTL I/O Supply Voltage.
Connect to either 1.8 or 3.3 V. When connected to
3.3 V, LVTTL compatible voltage swings are sup-
ported on the LVTTL inputs and LVTTL outputs of the
device.

Voltage Ref
Voltage Reference.
The Si5110 provides an output voltage reference that
can be used by an external circuit to set the LOS
threshold, slicing level, or sampling phase adjustment.
The equivalent resistance between this pin and GND
should not be less than 10 k Ω . The reference voltage
is nominally 1.25 V.
