3 Description
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.
