Low Power, Dual Lane Thunderbolt Retimer
General Description
The DS100TB211 is a dual lane low power bi-directional re-
timer with integrated signal conditioning for Thunderbolt cable
and peripheral applications. The DS100TB211 includes a ful-
ly adaptive input Continuous Time Linear Equalizer (CTLE),
clock and data recovery (CDR) and output de-emphasis (DE)
driver to ensure an error free operation over 2m+ of thin, in-
expensive 40-AWG copper cable with multiple connectors.
Each channel of the DS100TB211 independently locks to se-
rial data of 10.3125 Gbps (64b/66b encoded) without the need
for an external reference clock - This simplifies system design
and lowers overall cost.
Advanced cable diagnostic features such as on-chip receiver
eye processing on each of the input channel reduce manu-
facturing cost and time. Offered in a tiny 5mm x 5mm QFN
package and powered using a single 2.5v power supply, the
DS100TB211 consumes less than 250 mW per bi-directional
lane and can be implemented on a 6-layer paddle card board
design. The programmable settings can be applied easily us-
ing the I2C/SMBus interface.
