Overview
The PTN3381DBS,518 is a high-speed level shifter device produced by NXP USA Inc. This component is designed to convert four lanes of low-swing AC-coupled differential input signals to DVI v1.0 and HDMI v1.4b compliant open-drain current-steering differential output signals. It supports operation up to 3 Gbit/s per lane, making it suitable for applications requiring 36-bit deep color, 3D, and high-speed video transmission.
The device is fully integrated and includes an onboard 5 V regulator, enhancing its performance and power efficiency. It is functionally equivalent to the PTN3361D but offers improved high-speed performance with a programmable equalizer.
