DESCRIPTION
Typical Power Dissipation (EQ+DFE+CDR+DE):
180 mW / channel
The DS100DF410 is four channel retimers with
integrated signal conditioning. Each channel can
independently lock to 10.3125 Gbps data rate to
support 10GbE. The device includes a fully adaptive
Continuous-Time Linear Equalizer (CTLE), Clock and
Data Recovery (CDR) and transmit De-Emphasis
(DE) driver. The DS100DF410 also includes a self
calibrating 5-tap Decision Feedback Equalizer (DFE)
to enable data transmission over long, lossy and
crosstalk-impaired highspeed serial links to achieve

On-chip Eye Monitor (EOM), PRBS generator
Single 2.5 V ±5% power supply
SMBus/EEPROM configuration modes
Operating temperature range of -40 to 85°C
RHS 48-pin, 7 mm x 7 mm package
BER < 1×10-15
.
The programmable settings can be applied easily
using the SMBus (I2C) interface, or they can be
loaded via 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 DS100DF410 easy to
use.
Easy pin compatible upgrade between
repeater and retimers
