Additionally, the DS21348TN+ can be used for gigabit copper and fiber based networking, such as those commonly found in datacenters and server-to-switch communications.

Working Principle

The DS21348TN+ transceiver is based on a differential current-mode logic (DCML) signaling technique, where two levels of input and output signals are provided on a differential pair of terminals. The transceiver is equipped with two pairs of differential signaling paths, a transmit path and a receive path.

The transmit side utilizes differential current-mode logic (DCML) technique which converts the differential signal levels into two digital transmit pulse widths. The current-mode output pulses are then amplified and sent over the line. The receive side utilizes a differential comparator with body biasing to produce a complementary pair of digital output signals from the transmitted signals.

The transceiver is equipped with a clock-recovery circuit, providing additional margins for SONET/SDH signals. The clock-recovery circuit measures the average frequency of the input signal and adjusts the transmit clock frequency accordingly.

The transceiver also supports a variety of encoding schemes, including 8/10b line coding and the 8B/10B multilevel transmission scheme.

Conclusion

The DS21348TN+ transceiver is a versatile solution that provides physical layer connectivity over a wide range of high speed applications in the telecom and datacom fields. It is based on a differential current-mode logic (DCML) signaling technique, and is equipped with clock-recovery circuit and a variety of encoding schemes. The transceiver is ideal for a variety of applications, such as telecom and datacom equipment, server-to-switch connectivity and video backhaul.
