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.
