FM-VC Module

FM-VC FACE Module provide the ability for Video and Audio real and non-real time capture from low cost analog video sensors. Features A/V sampling, video, image processing and motion detection algorithms. In addition to application specific capabilities FM-VC offers several general purpose connectivity options as dual USB2.0 downstream ports and serial port supporting either single ended RS232 or differential mode RS485/RS422 operation.
FM-VC FACE Module designed for surveillance, homeland security and any other video analytic system.

Hardware Specifications

The following section provides information about FM-VC main components and features.

Intersil TW6869 Video Decoder The TW6869 is a highly integrated solution that supports multi-channel video and audio capture via PCI Express x1 interface for PC DVR system and video analytic application. It contains high quality eight channel NTSC/PAL/SECAM video decoders that convert analog composite video signal to digital component YCbCr data. Adaptive 4H comb filter for separating luminance and chrominance to reduce cross noise artifacts.
TW6869 contains a high performance proprietary DMA controller that fully optimizes the utilization of PCI Express x1 bandwidth and enables it to transfer video and audio data at a high throughput rate that closely approaches the theoretical limit of PCI Express x1 interface. TW6869 is able to simultaneously decode and transfer 8 real time video streams, or up to 16 channel non-real time video streams in FM-VC application, plus 8 real time audio channel.

SMSC SIO1007 Super-IO Controller The SMSC SIO1007 is PC 99 and ACPI 1.0 compliant Super I/O Controller. The SIO1007 implements the LPC interface with the LPC PortSwitch interface. The LPC PortSwitch interface is a hot switchable external docking LPC interface. It also features a full 16bit internally decoded address bus, a Serial IRQ interface with PCI clock support, relocatable configuration ports and three DMA channel options. The part also includes 16 GPIO pins. The SIO1007 incorporates one complete 8-pin UART. In addition SIO1007 provides a second UART to support a serial Infrared interface that complies with IrDA v1.2 (Fast IR) and several other popular IR formats. Main Features

  • One full function Serial port
  • High Speed UART with Send/Receive 16-Byte FIFOs
  • Support 230k and 460k Baud rates
  • Programmable baud rate generator
  • Modem control circuit
  • IR communication controller
  • LPC bus Host interface
  • LPC PortSwitch interface
  • Two IRQ input pins
  • PC99a and ACPI 1.0 Compliant
