Texas Instruments
Description
The TLK3114SC device is a flexible quad serial transceiver, delivering high-speed, bidirectional, point-to-point data transmissions to provide up to 10 Gbps of data transmission capacity. The TLK3114SC device is terminal compatible with the TLK3104SA quad serial transceiver and supports an 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 (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 TLK3114SC device performs the parallel-to-serial, serial-to-parallel conversion, and clock extraction functions for a physical layer interface. The TLK3114SC device also provides a selectable 8-b/10-b encode/decode function. The serial transmitter is implemented using differential pseudoemitter controlled logic (PECL) compatible signaling called voltage mode logic (VML) that eliminates the need for external components. The serial receiver employs an equalization circuit to maximize receive capabilities. The four transceivers in the TLK3114SC device can be configured as either four separate links or synchronized together as a single data path. The TLK3114SC device supports both the 32-bit data path, 4-bit control, 10-gigabit media independent interface (XGMII), and the extended auxiliary unit interface (XAUI) specified in the IEEE 802.3ae 10-Gigabit Ethernet standard. The TLK3114SC evice supports the IEEE 802.3 defined management data input/output (MDIO) interface to allow ease in configuration and status monitoring of the link. The TLK3114SC device supports the IEEE 1149.1 defined JTAG test port for ease in board manufacturing test. It also supports a comprehensive series of built-in tests for self-test purposes including internal serial loopback and pseudorandom bit stream (PRBS) generation and verification. The TLK3114SC device operates with a single 2.5-V supply and dissipates less than 3 W. The device is packaged in a 19x19 mm, 289-terminal plastic ball grid array (PBGA) package and is characterized for operation from 0°C to 70°C. The TLK3114SC device is a member of a family of CMOS multi-gigabit transceivers, intended for use in high-speed bidirectional point-to-point data transmission systems.
