7.1 Overview

The DS160PR822 is an eight-channel multi-rate linear repeater with integrated signal conditioning. The device provides quad 2x2 crosspoint mux functionality selectable by pin control or SMBus/I2C. The device's signal channels operate independently from one another. Each channel includes a continuous-time linear equalizer (CTLE) and a linear output driver, which together compensate for a lossy transmission channel between the source transmitter and the final receiver. The linearity of the data path is specifically designed to preserve any transmit equalization while keeping receiver equalization effective.

The DS160PR822 can be configured three different ways:

Pin Mode – device control configuration is done solely by strap pins. Pin mode is expected to be good enough for many system implementation needs.

SMBus/I2C Master Mode - device control configuration is read from external EEPROM. When the device has finished reading from the EEPROM successfully, it will drive the ALL_DONE_N pin LOW. SMBus/I2C slave operation is available in this mode before, during or after EEPROM reading. Note during EEPROM reading if the external SMBus/I2C master wants to access device registers it must support arbitration. The mode is prefferred when software implementation is not desired.

SMBus/I2C Slave Mode - provides most flexibility. Requires a SMBus/I2C master device to configure the device through writing to its slave address.
