The DS110RT410 is a four-channel retimer with integrated signal conditioning. The device includes a fully adaptive continuous-time linear equalizer (CTLE), clock and data recovery (CDR), and a transmit de-emphasis (DE) driver to enable data transmission over long, lossy and crosstalk-impaired highspeed serial links to achieve BER < 1 × 10–15. For channels with a high amount of crosstalk, the DS110DF410 should be used because it has self-calibrating 5-tap decision-feedback equalizer (DFE).
Each channel can independently lock to data rates from 8.5 to 11.3 Gbps, and associated sub-rates (divide by 2, 4, and 8) to support a variety of communication protocols. A 25-MHz crystal oscillator clock is used to speed up the CDR lock process. This clock is not used for training the PLL and does not need to be synchronous with the serial data.
The programmable settings can be applied using the SMBus (I2C) interface, or they can be loaded through an external EEPROM. An on-chip eye monitor and a PRBS generator allow real-time measurement of high-speed serial data for system bring-up or field tuning.
