DESCRIPTION
The TLK6201EA is a versatile, high-speed, limiting
equalizer for applications in digital high-speed links
with data rates up to 6.25 Gbps.
This device provides a high-frequency boost of 13
dB on the received data at 3.125 GHz, as well as
sufficient gain to ensure a fully differential output
swing for input signals as low as 100 mVp-p (at the
input of a lossy interconnect line).
Four de-emphasis levels can be selected on the
transmit side to provide up to 12 dB of additional
high-frequency loss compensation.
The high input-signal dynamic range ensures
low-jitter output signals even when overdriven with
input signal swings as high as 2000 mVp-p.
The TLK6201EA implements fixed loss-of-signal
detection, which can be used to implement a squelch
function by connecting the LOS output to the
adjacent DIS input.
The TLK6201EA is available in a small-footprint,
3-mm × 3-mm, 16-pin QFN package. It requires a
single 3.3-V supply.
This power-efficient equalizer is characterized for
operation from –40°C to 85°C.
