Hot-selling and scarce DS125DF410SQ/NOPB Low Power Multi-Rate Quad Channel Retimer WQFN48 spot stock

Product Descriptions

The DS125DF410 is four  channel    retimer  with integrated signal  conditioning. The device includes a fully  adaptive Continuous-Time Linear   Equalizer(CTLE),  self  calibrating 5-tap Decision Feedback Equalizer (DFE),  Clock and Data Recovery (CDR), and transmit De-Emphasis (DE) driver to enable data transmission over long, lossy and crosstalk-impaired highspeed serial links to achieve BER < 1× 10^-15 .

Each channel  can independently lock to data rate from 9.8 to 12.5 Gbps, and associated sub rates (div 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 via an external   EEPROM.  An on-chip eye monitor and aPRBS generator  allow real-time measurement  of high-speed serial  data for system bring-up or field tuning.
