PRODUCT BRIEF
INFORMATION
January 20, 2012
Low Power Multi-Rate Quad Channel Retimer
General Description
Features
■
The DS110RT410/DS110DF410 is a four-channel multi-rate
retimer with integrated signal conditioning. Both the
DS110RT410 and the DS110DF410 include an input Contin-
uous-Time Linear Equalizer (CTLE) on each channel. The
DS110DF410 also includes a five-tap Decision Feedback
Equalizer (DFE) on each channel.
All devices in the retimer family are pin compatible with
each other and with the quad buffer-repeater. The pin-
compatible device family includes the following:
DS100RT410 (EQ+CDR+DE): 10.3125 Gbps
DS100DF410 (EQ+DFE+CDR+DE): 10.3125 Gbps
DS110RT410 (EQ+CDR+DE): 8.5 - 11.3 Gbps
DS110DF410 (EQ+DFE+CDR+DE): 8.5 - 11.3 Gbps
DS125RT410 (EQ+CDR+DE): 9.8 - 12.5 Gbps
DS125DF410 (EQ+DFE+CDR+DE): 9.8 - 12.5 Gbps
DS100BR410 (EQ+DE): Up to 10.3125 Gbps

The DS110DF410 can enhance the reach and robustness of
long, lossy, crosstalk-impaired high speed serial links to
achieve BER < 1×10-15. For less demanding applications/in-
terconnects, the non-DFE variant DS110RT410 can be used
to achieve the same BER performance. The two devices are
pin-compatible.
Typical Power Dissipation (EQ+CDR+DE): 150 mW / chn
■
■
Each channel of the DS110RT410/DS110DF410 indepen-
dently locks to serial data at data rates from 8.5 to 11.3 Gbps
or to any supported submultiple of these data rates. A refer-
ence clock is not required, which simplifies system design and
lowers overall cost. Both the DS110RT410/DS110DF410
support half-rate, quarter-rate and one-eighth-rate for back-
ward compatibility. A protocol select mode is available to
speed up lock time.
Typical Power Dissipation (EQ+DFE+CDR+DE): 180

Locks to 1/2, 1/4, 1/8 legacy data rates

Fast lock operation based on protocol select mode
Adaptive equalization up to 34 dB boost at 5 GHz
Adjustable transmit VOD : 600 to 1300 mVp-p
Adjustable transmit de-emphasis to -12 dB
Programmable output polarity inversion
Input signal detection, CDR lock detection/indicator
On-chip Eye Monitor (EOM), PRBS generator
Single 2.5 V ±5% power supply
Programmable transmit de-emphasis (up to -12 dB), transmit
VOD (up to 1300 mVp-p) and adaptive receive equalization (up
to 34 dB boost at 5 GHz) enable data transmission over lossy
copper cables of typical lengths greater than 10 m or back-
planes with multiple connectors and typical trace lengths
greater than 40 inches. The CDR function is ideal for use in
parallel optical modules to reset the jitter budget and retime
high speed serial data.
SMBus/EEPROM configuration modes
Applications
The programmable settings can be applied easily using the
SMBus interface or they can be loaded via an external EEP-
ROM. 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.
