PTN3300B
DVI and HDMI level shifter
Rev. 01 — 8 July 2008 Product data sheet
1. General description
The PTN3300B 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 PTN3300B provides a single-ended active buffer for voltage translation of the HPD signal from 5 V on the sink side to 3.
