SDVO Connector
A low-profile 30-pin connector on the bottom of the ETX-N270 contains the set of SDVO (Serial Digital Video Out)
signals generated by the ETX-
N270’s IHC7-M chip.
SDVO, a high-speed serial digital video interface developed by Intel, is a standard feature of many of Intel
’s
newest PCI Express-enabled graphics controllers. SDVO uses differential signaling, and is capable of driving
CRT, DVI, LVDS, and TV-out devices. Specifically, the ETX-N270 s
upports the “SDVO B” signal set, as defined
by Intel.
Because the ETX 3.0 specification makes no provision for SDVO, the ETX-N270 provides an additional connector
for optional SDVO interfacing. The
board’s SDVO interface supports maximum data rates of 200 megapixels/sec.
The interface connector is Hirose part number FH-12-30S-0.5SH.
The SDVO connector’s signal pinout is shown
below.
