The DS64MB201 is a dual lane 2:1 multiplexer and 1:2 switch or fan-out buffer with signal conditioning suitable for SATA/SAS and other high-speed bus applications up to 6.4 Gbps. The device performs both receive equalization and transmit de-emphasis, allowing maximum flexibility of physical placement within a system. The receiver's continuous time linear equalizer (CTLE) provides a boost of up to +33 dB at 3 GHz and is capable of opening an input eye that is completely closed due to inter-symbol interference (ISI) induced by the interconnect medium. The transmitter features a programmable output de-emphasis driver and allows amplitude voltage levels to be selected from 600 mVp-p to 1200 mVp-p to suit multiple application scenarios. The signal conditioning settings are programmable via control pin settings or SMBus interface. To enable seamless upgrade from SAS/SATA 3.0 Gbps to 6.0 Gbps data rates without compromising physical reach, DS64MB201 automatically detects the incoming data rate and selects the optimal de-emphasis pulse width. The device detects the out-of-band (OOB) idle and active signals of the SAS/SATA specification and passes through with minimum signal distortion.

The DS78LS120QML is a high performance, dual differential, TTL compatible line receiver for both balanced and unbalanced digital data transmission. The inputs are compatible with EIA, Federal and MIL standards. The line receiver will discriminate a ±200 mV input signal over a common-mode range of ±10V and a ±300 mV signal over a range of ±15V. Circuit features include hysteresis and response control for applications where controlled rise and fall times and/or high frequency noise rejection are desirable. Threshold offset control is provided for fail-safe detection, should the input be open or short. Each receiver includes an optional 180Ω terminating resistor and the output gate contains a logic strobe for time discrimination. The DS78LS120QML is specified over a −55°C to +125°C temperature range. Input specifications meet or exceed those of the popular DS7820 line receiver.

TI’s Power-saver equalizer compensates for transmission medium losses and minimizes medium-induced deterministic jitter. Performance is guaranteed over the full range of 5 to 12.5 Gbps. The DS80EP100 requires no power to operate. The equalizer operates anywhere in the data path to minimize media-induced deterministic jitter in both FR4 traces and cable applications. Symmetric I/O structures support full duplex or half duplex applications. Linear compensation is provided independent of line coding or protocol. The device is ideal for both bi-level and multi-level signaling. The equalizer is available in a 6 pin leadless WSON package with a space saving 2.2 mm X 2.5 mm footprint. This tiny package provides maximum flexibility in placement and routing of the Power-saver equalizer.

The DS80PCI402 is a low-power, 4-lane repeater with 4-stage input equalization, and an output de-emphasis driver to enhance the reach of PCI-Express serial links in board-to-board or cable interconnects. This device is ideal for x4 (or lower) PCI-Express configuration, and it automatically detects and adapts to Gen-1, Gen-2, and Gen-3 data rates for easy system upgrade. DS80PCI402 offers programmable transmit de-emphasis (up to 12 dB), transmit VOD (up to 1300 mVp-p), and receive equalization (up to 36 dB) to enable longer distance transmission in lossy copper cables (10 meters or more), or backplanes (40 inches or more) with multiple connectors. The receiver can open an input eye that is completely closed due to inter-symbol interference (ISI) introduced by the interconnect medium. The programmable settings can be applied easily through pins or software (SMBus/I2C), or can be loaded through an external EEPROM. When operating in the EEPROM mode, the configuration information is automatically loaded on power up, which eliminates the need for an external microprocessor or software driver.
