ADVANCE INFORMATION March 7, 2012 Low Power, Dual Lane Thunderbolt Retimer General Description Features The DS100TB211 is a dual lane low power bi-directional retimer with integrated signal conditioning for Thunderbolt cable and peripheral applications. The DS100TB211 includes a fully 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, inexpensive 40-AWG copper cable with multiple connectors. Each channel of the DS100TB211 independently locks to serial 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 manufacturing 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 using the I2C/SMBus interface. Notice: This document is not a full datasheet.
