The TLK3104SA is a flexible four-channel serial backplane transceiver, delivering high-speed bidirectional point-to-point data transmissions to provide up to 10 Gbps of full duplex data transmission capacity. The TLK3104SA supports a broad operating range of serial data rates from 2.5 Gbps to 3.125 Gbps. The primary application of this device is to provide building blocks for developing point-to-point baseband data transmission over controlled impedance media of approximately 50 . The transmission media can be printed-circuit-board 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 TLK3104SA performs the parallel-to-serial, serial-to-parallel conversion, and clock extraction functions for a physical layer interface. The TLK3104SA also provides a selectable 8-bit/10-bit (8b/10b) encode/decode function. The serial transmitter and receiver is implemented using differential pseudo-emitter coupled logic (PECL) compatible signaling called voltage mode logic (VML) that eliminates the need for external components. The four transceivers in the TLK3104SA can be configured as either four separate links, or synchronized together as a single data path. The TLK3104SA supports both the 32-bit data path, 4-bit control, 10 gigabit media independent interface (XGMII) and the extended auxiliary unit interface (XAUI) currently proposed in the IEEE 802.3ae 10 gigabit ethernet task force. Figure 1 shows an example system block diagram for the TLK3104SA used as an XGMII extended sublayer (XGXS) device to provide an additional trace distance on PCB for data being transferred between the switching fabric and optical transceiver modules.
