Equaliser supports all 10G/8G interface
standards
Flexible high-speed equaliser extends the reach of printed circuit board signal channels, such as backplanes or active copper cables.
Texas Instruments has introduced a flexible high-speed equaliser to extend the reach of printed circuit board signal channels, such as backplanes or active copper cables With multirate operation up to 11.3Gbit/s, the new equaliser supports all 10G/8G interface standards

RF platform brings three radios together
Texas Instruments has developed the industry's first solution that integrates mobile WLAN (mWLAN), Bluetooth and FM stereo audio all in a space-saving platform for mobile phones.
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).
The TLK1101E features excellent loss of compensation to deliver high signal integrity in target applications.
For example, the equaliser provides 30dB of loss compensation to support up to 20m of 24AWG cable or up to 40in of FR-4 printed circuit board trace at data transmission rates up to 11.3Gbit/s, with only 0.13 unit intervals of deterministic jitter at the equaliser output.
The device also provides up to 7dB transmitter de-emphasis to further compensate for loss of up to 12in of FR-4 board interconnect.
The TLK1101E is highly programmable and allows one single device to be configured for its optimum performance under various datarates and various channel lengths.
The output differential voltage swing can be set to 300, 600 or 900mV peak-peak.
The interconnect length can be set from 0 to 20m of 24AWG 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 cutoff is low enough to support low-frequency control signals such as SAS and SATA out-of-band signals.
TI provides a wide selection of high speed equalisers for cables and printed circuit boards.
The low-jitter devices compensate for channel loss at various datarates in high-speed links for communications and data systems.
The TLK1101E is available now in a 20-pin QFN package, priced at US $12.35 in 100-unit quantities.
In addition, samples and evaluation modules (EVMs) are available.
