Description
Pericom Semiconductor’s PI3VDP411LSA provides the ability
to use a Dual-mode DisplayPort™ transmitter in HDMI™ mode.
This flexibility provides the user a choice of how to connect to
their favorite display. All signal paths accept AC coupled video
signals. The PI3VDP411LSA converts this AC coupled signal into
an HDMI rev 1.3 compliant signal with proper signal swing. This
conversion is automatic and transparent to the user.
Output squelch function is provided for each channel. When out-
put channel is enable (OE#=0) and operating, that TMDS pixel
clock input signal determines whether the output is enabled.
When no TMDS pixel clock is present, TMDS output channel
will be disabled.
The PI3VDP411LSA supports up to 2.5Gbps, which provides 12-
bits of color depth per channel, as indicated in HDMI rev 1.3.
