Equalizer offers up to 11.3 Gbps multi-rate operation.

Press Release Summary:

Supporting all 10G/8G interface standards, Model TLK1101E features 2-wire serial interface, pin control, and PC-based GUI. Equalizer provides 30 dB of loss compensation to support up to 20 m of 24 AWG cable or up to 40 in. of FR-4 printed circuit board trace, and also provides up to 7 dB transmitter de-emphasis to further compensate for loss of up to 12 in. of FR-4 board interconnect. Output differential voltage swing can be set to 300, 600, or 900 mVp-p.

TI Expands High-Speed Equalizer Family with Industry's Lowest Jitter, Multi-Rate 11.3-Gbps Equalizer

Flexible GUI Eases Active Copper Cable and Backplane Design Implementation

DALLAS, Dec. 11 -- Texas Instruments (TI) (NYSE:TXN) today introduced a flexible high-speed equalizer to extend the reach of printed circuit board signal channels, such as backplanes or active copper cables. With multi-rate operation up to 11.3 Gbps, the new equalizer supports all 10G/8G interface standards. The device's two-wire serial interface, pin control and PC-based graphical user interface (GUI) enable very quick prototyping, which significantly reduces the development cycle for high-performance computers, storage subsystems, telecommunications equipment and automatic test equipment (ATE). (See http://www.ti.com/tlk1101e-pr.)

The TLK1101E features excellent loss of compensation to deliver high signal integrity in target applications. For example, the equalizer provides 30-dB of loss compensation to support up to 20 m of 24-AWG cable or up to 40 in. of FR-4 printed circuit board trace at data transmission rates up to 11.3 Gbps, with only 0.13 unit intervals of deterministic jitter at the equalizer output. The device also provides up to 7 dB transmitter de-emphasis to further compensate for loss of up to 12 inches of FR-4 board interconnect.

The TLK1101E is highly programmable and allows one single device to be configured for its optimum performance under various data rates and various channel lengths. The output differential voltage swing can be set to 300 mVp-p, 600 mVp-p, or 900 mVp-p. The interconnect length can be set from 0 to 20 m of 24-AWG twinaxial cable. The input threshold voltage and the loss of signal assert level can also be adjusted. Those settings can be made either through control pins or the two-wire serial control interface. The low-frequency cut-off is low enough to support low-frequency control signals such as SAS and SATA out-of-band signals.

High-Speed Equalizer Family

TI provides a wide selection of high speed equalizers for cables and printed circuit boards. The low-jitter devices compensate for channel loss at various data rates in high-speed links for communications and data systems.
