THS6042CDR is a low-power, high-speed, dual-channel differential receiver that supports up to 5.6 Gbps of input data rate. The device features automatic data rate detection, enabling it to recover data from random jitter and/or random data patterns. It is designed to be used in data communications systems with differential inputs, such as PCI Express, InfiniBand and Fibre Channel, as well as in other data communications systems.

The THS6042CDR integrates a fully-differential receiver, programmable pattern detection capabilities, a programmable voltage reference, output de-emphasis and data rate detection circuitry. It is available in an industry-standard 10-lead Plastic TSSOP package, requiring only two external resistors for data rate initialization.

The THS6042CDR application field and working principle provide the core set of capabilities necessary to optimize high-speed data recovery performance. The device provides on-chip adaptive data rate detection and selectable output levels, programmable de-emphasis and programmable jitter rejection. It also offers automatic frequency drift and/or input transition jitter synchronization. Additionally, the device provides adjustable low-swing detect thresholds over a wide range of data rates. All of these features make the THS6042CDR suitable for high-speed, low-power receiver applications.

First, the THS6042CDR operates on a differential receiver with RSSI (Receive Signal Strength Indicator) technique, which is combined with forward-path equalizer (FPE) and automatic data rate detection for improved signal integrity. By using RSSI and FPE, the device can automatically adjust internal equalization based on the input signal strength and its frequency. Furthermore, the device includes a selectable output shift logic level for low-swing detect, which reduces power consumption and enhances data rate recovery. Additionally, the device features programmable pattern detection for improved signal integrity and noise immunity.

Second, the THS6042CDR includes programmable data rate settings, enabling operation from 1.54 Gbps to 5.6 Gbps of input data rates. The device provides an additional 15% cushion zone, plus/minus difference in symbol clock frequencies. All these features are optimized for signal integrity, signal reliability, robustness, scalability and power efficiency.

Third, the THS6042CDR offers a programmable voltage reference, adjustable de-emphasis and adjustable jitter rejection, which can be adjusted via external resistor settings. The device supports a wide range of data rates, including rates up to 5.6 Gbps, and helps reduce design complexity and improve signal integrity.

Finally, the THS6042CDR utilizes a single-chip, dual-channel solution with both channels operating from the same supply voltage. This reduces board space by eliminating the need for two separate chips, and reducing the complexity of the design. The THS6042CDR is also available with a variety of packages, which can be used for board-level mounting flexibly.

In summary, the THS6042CDR is a differential receiver that provides low-power, high-speed signal conditioning, allowing for improved signal integrity, superior data rate recovery and scalability. It is suitable for a wide range of applications, including infiniband, fibre channel, and other data communication systems. The device also reduces complexity and board space requirements, enabling manufacturers and designers to develop smaller, more efficient systems.
