PTN3361B Datasheet Hdmi/dvi Level Shifter

Manufacturer: NXP Semiconductors

Overview: PTN3361B HDMI/DVI level shifter with dongle detect support and active DDC buffer Rev. 02 — 7 October 2009 Product data sheet 1.

General Description

The PTN3361B 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 v1.3a compliant open-drain current-steering differential output signals, up to 1.65 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 PTN3361B 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

  • supporting HDMI dongle detection and active DDC buffering. For HDMI dongles, support of HDMI dongle detection via the DDC channel is mandatory, hence HDMI dongle.
