SingMai introduces DP1
SingMai Electronics has introduced the DP1, an audio/video interface card that provides
analogue connectivity to Altera and 3rd party FPGA development boards utilizing the Santa Cruz connectors, (e.g. http://www.altera.com/products/devkits/altera/kit-nios-2c35.html). The board provides a high quality analogue/digital interface capability for the development of audio and video processing algorithms for applications in consumer electronics, security, broadcast and general purpose image processing.
DP1 provides three 10-bit video ADCs using Analog Devices AD9981 I.C. that allow conversion of SD and HD analogue video in a variety of formats to digital video for processing by the development board FPGA. In addition clocks and sync signals can be extracted from the input video.
Output video processing is provided the ADI ADV7321 which provides simultaneous RGB/YPbPr outputs, again for SD and HD video, as well as composite video outputs.
Audio interfacing is provided via another ADI codec. Stereo analogue audio is converted to I2S using a 24-bit ADC whilst a high quality stereo DAC provides output analogue capability.
The board provides all the necessary input and output buffering, power and interfacing for these ICs and also incorporates a free-running 27MHz crystal output.
All digital inputs and outputs are provided to the development board's FPGA and example designs and register sets are provided, including a simple I2C driver.
The board is also supported by a range of video and audio intellectual design blocks for Altera FPGAs which are also available from SingMai Electronics. These include NTSC and PAL decoders and encoders, video character generators and pattern generators, and video noise reducers.
SingMai Electronics is a Canadian start-up company that will be utilizing its thirty years of electronics design expertise to provide customers with innovative and cost-effective solutions to their video and audio processing requirements.
