DESCRIPTION
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
settable from 0 to 7dB, the output differential voltage swing settable from 225 to 1200mV
p-p
, the input
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
the input filter bandwidth settable from 4.5 to 11GHz, and
the LOS (loss of signal) assert voltage level.
