Enhanced performance HDMI/DVI level shifter with active DDC

Product data sheet
1. General description
The PTN3360D 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 compliant open-drain
current-steering differential output signals, up to 3.0 Gbit/s per lane to support 36-bit
deep color mode, 4K 2K video format or 3D video data transport. 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 to 3.3 V on the sink side. Additionally, the
PTN3360D 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. The DDC channel is implemented using
active I2C-bus buffer technology providing capacitive isolation, redriving and level shifting
as well as disablement (isolation between source and sink) of the clock and data lines.
The low-swing AC-coupled differential input signals to the PTN3360D typically come from
a display source with multi-mode I/O, which supports multiple display standards, for
example, DisplayPort, HDMI and DVI. While the input differential signals are configured to
carry DVI or HDMI coded data, they do not comply with the electrical requirements of the
DVI v1.0 or HDMI v1.4b specification. By using PTN3360D, chip set vendors are able to
implement such reconfigurable I/Os on multi-mode display source devices, allowing the
support of multiple display standards while keeping the number of chip set I/O pins low.
See Figure 1.
The PTN3360D main high-speed differential lanes feature low-swing self-biasing
differential inputs which are compliant to the electrical specifications of DisplayPort
Standard v1.2 and/or PCI Express Standard v1.1, and open-drain current-steering
differential outputs compliant to DVI v1.0 and HDMI v1.4b electrical specifications. The
I2C-bus channel actively buffers as well as level-translates the DDC signals for optimal
capacitive isolation. The PTN3360D also supports power-saving modes in order to
minimize current consumption when no display is active or connected.
The PTN3360D is a fully featured HDMI as well as DVI level shifter. The PTN3360D
supersedes PTN3360B, and provides a better high speed performance with a
programmable equalizer.
PTN3360D is powered from a single 3.3 V power supply consuming a small amount of
power (230 mW typical) and is offered in a 48-terminal HVQFN48 package.
