The DS160PR410 device is a low-power high-performance linear repeater / redriver designed to support PCIe Gen-1, 2, 3, and 4. The receivers continuous time linear equalizer (CTLE) provides a programmable high-frequency boost followed by a linear output driver. The CTLE receiver can open an input eye that is completely closed due to inter-symbol interference (ISI) induced by an interconnect medium, such as PC board traces or twin-axial copper cables. The programmable equalization maximizes the flexibility of physical placement within the interconnect channel and improves overall channel performance.
The DS160PR410 preserves transmit preset signal characteristics, thereby allowing the host controller and the end point to negotiate transmit equalizer coefficients. This transparency in the link training protocol facilitates system level interoperability and minimizes latency.
The programmable settings can be applied easily through software (SMBus or I2C), direct loading from an external EEPROM, or by using pin control. In EEPROM mode, the configuration information is automatically loaded on power up, thereby eliminating the need for an external microprocessor or software driver.
