PTN3381D Datasheet Enhanced Performance Hdmi/dvi Level Shifter

Manufacturer: NXP Semiconductors

Overview: PTN3381D Enhanced performance HDMI/DVI level shifter with voltage regulator, dongle detection and supporting 3 Gbit/s operation Rev. 2 — 26 July 2012 Product data sheet 1.

General Description

The PTN3381D is a high-speed level shifter device which converts four lanes of low-swing AC-coupled differential input signals to DVI v1.0 and HDMI v1.4b pliant open-drain current-steering differential output signals, up to 3 Gbit/s to support 36-bit deep color, 3D and 3 Gbit/s modes.

Each of these channels provides a level-shifting differential buffer to translate from low-swing AC-coupled differential signaling on the source side, to TMDS-type DC-coupled differential current-mode signaling terminated into 50  to 3.3 V on the sink side.

Additionally, the PTN3381D provides a single-ended active buffer for voltage translation of the HPD signal from 5 V on the sink side to 3.3 V on the source side and provides a channel with active buffering and level shifting of the DDC channel (consisting of a clock and a data line) between 3.3 V source-side and 5 V sink-side.

Key Features

  • 2.1 High-speed TMDS level shifting.
  • Converts four.
