The TLK1102E is a versatile and flexible high-speed dual-channel equalizer for applications in digital high-speed

links with data rates up to 11.3Gbps.

The TLK1102E can be configured in many ways through its two-wire serial interface, available through the SDA

and the SCL pins, to optimize its performance. The configurable parameters include the output de-emphasis

equalization level settable for 0 to 20 meters of 24-AWG twinaxial cable, 0 to 40 inches of FR-4 PCB

interconnect, or equivalent interconnect (see Table 1), the input filter bandwidth settable from 4.5 to 11GHz, and

the LOS (loss of signal) assert voltage level.
