Description
AI
The DS100RT410 is a four-channel retimer with integrated signal conditioning. Each channel can independently lock to 10.3125-Gbps data rate to support 10 GbE. 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 DS100DF410 should be used because it has self-calibrating 5-tap decision-feedback equalizer (DFE).
The programmable settings can be applied easily 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. Flow-through pinout and single power supply make the DS100RT410 easy to use.
