PTN3392
2-lane DisplayPort to VGA adapter IC
7.4.1 S0 = logic 0
If S0 is left open-circuit (internal pull-down) (DisplayPort v1.1a compliant behavior),
PTN3392 behaves as stated in VESA DisplayPort v1.1a, sections 7 and 8. PTN3392 will
keep HPD LOW during its internal initialization sequence after power-up. It will then
update DPCD register SINK_COUNT to the expected value, depending if a VGA monitor
is detected or not, and will then assert HPD HIGH whatever is the value of SINK_COUNT
register. Each time PTN3392 detects a change in the VGA monitor connection status, it
will update the SINK_COUNT register accordingly, set
DOWNSTREAM_PORT_STATUS_CHANGED register bit to 1 and generate IRQ_HPD
pulse to signal the source about the status change. Refer to Figure 3, S0 = LOW
flowchart.
7.4.2 S0 = logic 1
If S1 is tied to HIGH with external pull-up (best interoperability behavior), the PTN3392 will
keep HPD LOW during its internal initialization sequence after power-up. It will then wait
for a VGA monitor to be connected downstream before asserting HPD HIGH to force
source waiting for a VGA monitor before starting protocol negotiations. If a VGA monitor is
disconnected during normal operations, PTN3392 will assert HPD LOW so that the source
will consider that no sink device is connected anymore. Refer to Figure 3, S0 = HIGH
flowchart.
7.5 EDID handling
Figure 4 shows a DisplayPort-to-analog video converter (or dongle) situated between the
DisplayPort source and a VGA monitor. The PTN3392 converts a DP I2C Over AUX
request to I2C on the monitor's DDC bus. The monitor's EDID read data is then returned to
the DP source via an I2C Over AUX response issued by the PTN3392.
It is the responsibility of the source to only choose video modes which are declared in the
EDID and to adjust the DisplayPort link capabilities (link rate and lane count) to provide
the necessary video bandwidth. The PTN3392 does not cache or modify the EDID to
match the capabilities of the DisplayPort link data.
If the DisplayPort source drives display modes that are not specified in the EDID mode
list, the PTN3392 will not detect such conditions, and will display at its output what it is
presented by the DisplayPort source.
