Serial Interface for Transceiver

Control

The Serial Interface for

Transceiver Control (STC) is used

to control and program the

features of the transceiver. These

features include input/output

(I/O) control, optical power

adjustment and shut down.

The STC requires three signals: a

serial clock (SCLK) that is used

for timing, and two unidirectional

lines multiplexed with the

transmitter (write) TXD/SWDAT

and receiver (read) RXD/SRDAT

infrared signal lines.

The HSDL-3210 supports the

write function to disable/enable

the TXD line, disable/enable the

RXD line and 4-level optical

power adjustment.

A set of commands is provided to

handle the programming control

features. The general command

format is shown in Figure 3. The

HSDL-3210 STC Write Data

Commands are shown in Table 1.
