TLK4201EA

4.25Gbps 电缆和 PC 主板均衡器

The 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 100 mVP-P at the input of the interconnect line or cable.

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 TLK4201EA includes fixed loss-of-signal LOS detection, which can be used to implement a squelch function by connecting the LOS output to the adjacent DISABLE input. The LOS function can be disabled by pulling LOSDIS to high level.

The TLK4201EA is available in a small-footprint, 3-mm ×; 3-mm, 16-pin QFN package. It requires a single 3.3-V supply.

This very power-efficient equalizer is characterized for operation from -40°C to 85°C.
