Description STDP31002/7 Doc ID 15121 Rev 2
1 DescriptionSTDP3100 is a DisplayPort to VGA signal format converter for interfacing next generation
DisplayPort based PC and notebook computers with conventional VGA displays, such as
CRT, LCD monitors, and projectors. DisplayPort offers a unified, scalable, and cost effective
interface for embedded and external display applications. As desktop and notebook PCs are
increasingly transitioning from conventional analog type interfaces to DisplayPort,
STDP3100 facilitates the transition by offering seamless connectivity between new
DisplayPort PC and notebooks and the installed base VGA monitors and projectors.
STDP3100 is a highly integrated converter featuring a DisplayPort receiver, video DAC,
clock form generator, test pattern generator, and sink detection block. In addition,
STDP3100 includes EDID and MCCS pass-through features, forming a fully transparent
operation between the PC and display. Active power consumption of this device is as low as
400mW, and thus it can be powered by the DisplayPort source when used in dongle
application. The device has a built in sink detection feature that determines the active and
standby state. The device enters into standby (low power) state whenever the VGA cable is
disconnected and returns to normal operation when the cable is connected back.
STDP3100 supports video resolutions from VGA through WUXGA. The input DisplayPort
interface consists of two main lanes, AUX channel, and HPD signal that maps directly to a
standard DisplayPort connector via two layers PCB. The output interface consists of analog
R, G, B video, Hsync, Vsync, and DDC signals. Analog video signal amplitude ranges from 0
to 700mV from a 10 bit video DAC with maximum sampling frequency of 162 MHz. The VGA
output signal interface conforms to the VSIS standards with separate Hsync and Vsync
control signals. The DDC_SDA and DDC_CLK signals are driven from an I2C master, which
controls I2C traffic between the DisplayPort AUX channel and external slave device.
ST offers STDP3100 designers kit with complete reference hardware and firmware.
