DESCRIPTION
The TLK4211EA is a versatile high-speed limiting equalizer for applications in digital high-speed links with data
rates up to 4.25 Gbps.
This device provides a high frequency boost of 12 dB at 2.1 GHz as well as sufficient gain to ensure a fully
differential output swing for input signals as low as 200 mVp-p (at the input of the interconnect line).
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 TLK4211EA 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.
