TLK4201EARGTR Description

Short technical summary and product information.

The Texas Instruments TLK4201EARGTR is a versatile, high-speed limiting equalizer engineered for digital high-speed links operating at data rates up to 4.25 Gbps. This device provides a significant high-frequency boost, compensating for signal loss in cables and PC boards.

 

Key electrical specifications include a signaling rate of 4250 Mbps, AC-coupled input and output signals, and CML output protocols. It features a single 3.3V supply requirement and operates within a temperature range of -40°C to 85°C. The equalizer can compensate for up to 12 dB of loss at 2.1 GHz, making it suitable for receiving 4.25 Gbps data over up to 36 inches of FR4 PC boards or 30 feet of CX4 cable.

 

Packaged in a compact 16-VQFN (3x3 mm) surface-mount configuration, the TLK4201EARGTR is designed for applications such as Fibre Channel systems (1.0625-Gbps, 2.125-Gbps, and 4.25-Gbps), high-speed links in communication and data systems, backplane interconnects, and rack-to-rack interconnects. Additional features include ultralow power consumption, input offset cancellation, high-input dynamic range, output disable, output polarity select, selectable loss-of-signal detection, and selectable squelch function.
