Note
The optional DDI interface (DDI2) will not function if LVDS is enabled in the BIOS setup menu.
5.1.3
VGA
The conga-TCA3 offers one VGA interface on the A–B connector rows. The VGA port provides RGB signal output as well as HSYNC and VSYNC
signal, with dedicated DDC signal pair.
The analog VGA display interface has a RAM-based Digital-to-Analog Converter (RAMDAC). The 320 MHz RAMDAC integrated in the SoC
supports resolution up to 2560 x 1600 at 60 Hz refresh rate.
5.1.4
Serial ATA™ (SATA)
The conga-TCA3 offers two SATA interfaces on the A–B connector. The interfaces support:
•
independent DMA operation
•
data transfer rates up to 3.0 Gb/s
•
legacy and AHCI mode
5.1.5
USB 2.0
The conga-TCA3 offers eight USB 2.0 interfaces on connector rows A–B. Four of these ports are routed directly from the SoC to the A–B
connector.The other four ports are routed to the A–B connector via a 4-port USB HSIC hub.
The EHCI host controller in the SoC supports these interfaces with high-speed, full-speed and low-speed USB signalling. The controller
complies with USB standard 1.1 and 2.0. For more information about how the USB host controllers are routed, see section 7.3 "USB Port
Mapping".
Note
According to an Intel Errata, the SoC's HSIC port 0 is reset and re-enumerated when a device is connected or disconnected from USB port 0
during runtime. For this reason, end users should not disconnect or connect any USB device to USB port 0 at runtime. Doing so may cause
USB ports 4-7 (ports routed via USB 2.0 hub) to malfunction.
