DESCRIPTION
The TLK1101E is a versatile and flexible high-speed equalizer for applications in digital high-speed links with
data rates up to 11.3Gbps.
The TLK1101E can be configured in many ways to optimize its performance. It provides output de-emphasis
adjustable from 0dB to 7dB using pins DE0 and DE1.
The output differential voltage swing can be set to 300mV_p-p, 600mV_p-p, or 900mV_p-p using the SWG pin. A
controlling voltage on pin VTH can be used to adjust the input threshold voltage.
Pins LN0 and LN1 can be used to optimize the device performance for various interconnect lengths, e.g. from 0
to 20 meters of 24-AWG twinaxial cable.
The LOS (loss of signal) assert level can be set to a desired level through a controlling voltage connected to pin
LOSL. The LOS assert levels can be chosen from two LOS assert level ranges selectable with the LOSR pin.
