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.
