TI introduces flexible, quad SerDes device with integrated clock jitter cleaner


Ultra-wide speed range makes it easy for designers to implement various communications standards with one device

DALLAS .- Texas Instruments (TI) (NYSE: TXN) today 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.

Quad SerDesd with integrated clock jitte

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 SerDesí 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 TIís family of SerDes devices, including the TLK2541 device for EPON optical line terminals and TLK1221 Gigabit Ethernet transceiver. They contribute to TIís broad interface product offering, which includes families of products for M-LVDS, LVDS, CAN, I2C, ESD, RS-485, RS-232 and PCI-Express standards. Please see for more information. TI also offers the complete portfolio of analog front end, embedded processors, software and evaluation modules for all wireless infrastructure air interfaces at


The TLK3134 is available now in a 289-pin BGA package, priced at $35.00 in 1,000-unit quantities. In addition, samples are available online today at
