PTN3300A Datasheet Dvi/hdmi Level Shifter

Manufacturer: NXP Semiconductors

Overview: www.DataSheet4U.com PTN3300A DVI/HDMI level shifter with inverting 1.1 V HPD Rev. 01 — 30 June 2008 Product data sheet 1.

General Description

The PTN3300A is a high-speed level shifter device which converts four lanes of low-swing AC-coupled differential input signals to DVI and HDMI compliant open-drain current-steering differential output signals, up to 2.25 Gbit/s per lane.

Each of these lanes 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 Ω to 3.3 V on the sink side.

Additionally, the PTN3300A provides a single-ended active inverting buffer for voltage translation of the HPD signal from 5 V on the sink side to 1.1 V on the source side and provides a channel for 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

  • supporting DVI and HDMI. It is identical to the PTN3300B except that the HPD_SOURCE_N output is the logic inverse function of input HPD_SINK, level shifted to 1.1 V. For a fully-featured HDMI/DVI level shifter function that supports active buffering of the DDC lines and HDMI dongle detect, the PTN3301 should be used. PTN3300A is powered from a single 3.3 V power supply consuming a small amount of power (120 mW typ. ) and is offered in two different 48-terminal HWQFN packages, one laminate based (.
