TI Introduces Flexible, Quad SerDes Device with Integrated Clock Jitter Cleaner

Texas Instruments (TI) has introduced a four-channel serializer/deserializer (SerDes) integrated circuit that enables high-speed, bi-directional, point-to-point data transmission with up to 30 Gbps. The device has the flexibility to be configured either as a XAUI or 10 GFC transceiver. This multi-rate transceiver supports a wide data bandwidth range from 600 Mbps to 3.75 Gbps per serial lane to address design challenges in a variety of applications such as gigabit Ethernet links or backplane and front plane connections.

The TLK3134 performs the parallel-to-serial, serial-to-parallel conversion and clock extraction functions for a physical layer interface, all in one compact device. The integrated reference clock jitter cleaner significantly eases the design process and allows the use of an economical reference clock source. The device meets the CPRI and OBSAI specifications for wireless infrastructure equipment. The backplane reach and transmission distance over cable can be extended by this SerDes’ serial side transmit de-emphasis and adaptive receiver equalization.

Other key features include the following:
Supports independent channel SerDes operation modes in 8-/10-bit data modes (TBI and 8-bit + control)
Supports 10 GbE (XAUI), 1X/2X/10X fibre channel, CPRI (x1/x2/x3), OBSAI (x1/x2/x4), and 1 GbE (1000 Base-X) data rates
10 GbE XGXS (XAUI) compliant core and 1000 Base-X PCS support

The TLK3134 transceiver complements TI’s family of SerDes devices, including the TLK2541 device for EPON optical line terminals and TLK1221 Gigabit Ethernet transceiver. They contribute to TI’s broad interface product offering, which includes families of products for M-LVDS, LVDS, CAN, I2C, ESD, RS-485, RS-232 and PCI-Express standards.
