The receiver component converts the optical serial data into PECL compatible electrical
data (RD+ and RD–). The Signal Detect (SD, active high) shows whether an optical
signal is present.
The transmitter converts electrical PECL compatible serial data (TD+ and TD–) into
optical serial data.
The following versions are available:
1 AC/DC Transceiver: Tx is AC coupled. Differential 100 Ω load. Rx has standard PECL
output and is DC coupled.
2 AC/AC TTL Transceiver: Tx and Rx are AC coupled. Tx has differential 100 Ω load.
Signal Detect is TTL compatible.
3 DC/DC Transceiver: Standard PECL inputs and outputs Tx and Rx are DC coupled.
This version contains an Input Signal Monitor (ISM) which switches off the transceiver
if a continuous low level is applied at Data Input.
4 AC/AC PECL Transceiver: Tx and Rx are AC coupled. Tx has differential 100 Ω load.
Signal Detect is PECL compatible.
