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.
