Overview
The PTN3361BBS,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 v1.3a compliant open-drain current-steering differential output signals. It supports data rates up to 1.65 Gbit/s per lane and can be enhanced to 2.25 Gbit/s per lane using a pre-emphasis feature. The device is particularly useful in applications requiring the translation of signals from sources with multi-mode I/O, such as DisplayPort, HDMI, and DVI, to comply with the electrical requirements of DVI and HDMI standards.
