The TLK3132 is a flexible two channel independently configurable serial transceiver. It can be configured to be compliant with the 1000Base-X 1Gbps Ethernet Specification (Auto-Negotiation not supported). The TLK3132 provides high-speed bi-directional point-to-point data transmissions with up to 15 Gbps of raw data transmission capacity. The primary application of this device is in backplanes and front panel connections requiring 3.75Gbps connections over controlled impedance media of approximately 50. The transmission media can be printed circuit board (PCB) traces, copper cables or fiber-optical media. The ultimate rate and distance of data transfer is dependent upon the attenuation characteristics of the media and the noise coupling into the lines.

The TLK3132 performs the parallel-to-serial, serial-to-parallel conversion, and clock extraction functions for a physical layer interface. The TLK3132 also provides 1000Base-X (PCS) layer functionality described in Clause 36 of 802.3-2002. The serial transmitter is implemented using differential Current Mode Logic (CML) with integrated termination resistors.

Many common applications may be enabled by way of externally available control pins. Detailed control of the TLK3132 on a per channel basis is available by way of accessing a register space of control bits available through a two-wire access port called the Management Data Input/Output (MDIO) interface.Read more
