PTN3381B - Enhanced performance HDMI/DVI level shifter

Description

The PTN3381B 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.

Features

  • 2.1 High-speed TMDS level shifting.
  • 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.
  • Pin-programmable pre-emphasis feature.

PTN3381B Enhanced performance HDMI/DVI level shifter with voltage regulator, dongle detect support and active DDC buffer Rev. 2 — 15 October 2010 Product data sheet 1. General description The PTN3381B 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.
