Low Power 10GbE Quad Channel Retimer

General Description

The DS100RT410/DS100DF410 is a four-channel 10GbE re-

timer with integrated signal conditioning. Both the

DS100RT410 and the DS100DF410 include an input Contin-

uous-Time Linear Equalizer (CTLE) on each channel. The

DS100DF410 also includes a five-tap Decision Feedback

Equalizer (DFE) on each channel.

The DS100DF410 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 DS100RT410 can be used

to achieve the same BER performance. The two devices are

pin-compatible.

Each channel of the DS100RT410/DS100DF410 indepen-

dently locks to 10GbE serial data at a data rate of 10.3125

Gbps or to 1GbE data at a data rate of 1.25 Gbps. A reference

clock is not required, which simplifies system design and low-

ers overall cost. Both devices support either data rate. A

protocol-select mode is available to speed up lock time.

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.

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.

The device is offered in a 48-pin LLP, 7 mm x 7 mm flow-

through package.
