CRD7666-7C
Analog/Digital Evaluation CCD Cameras
Features Description
The CRD7666-7C is a CCD camera that provides a simple to use evaluation and demonstration platform using the CS7615 which performs CDS and analog-to-digital conversion of the CCD signal and the CS7666 which converts the digitized CCD output data into the international standard 4:2:2 digital video conforming to H.656 transport protocol. Also included is a CS4954 video encoder that converts 4:2:2 digital video to analog NTSC/PAL video and S-Video. The board set produces simultaneous digital AND analog video outputs. Analog output requires a standard video monitor. Control software is included to adjust camera settings and operational features. In order to view the digital video, a cable and a PCI card are provided as well as viewing software on CD-ROM. The camera consists of two boards (1) CCD+Video processing board and (2) video encoder board. All cameras include external power module, parallel port I2C controller and control software to adjust camera settings and operational features. Digital output is provided via a 26-pin connector and the NTSC/PAL output is via standard RCA and S-Video connectors. ORDERING INFORMATION CRD7666-7C

CRD7666-7C
OPERATION
The CCD+Video processing board includes the CS7615 Analog Video Signal Processor which performs analog processing and converts the analog CCD output to a digital format. Also included on the processor board is the CS7666 Digital Video Color-Space Processor, which decodes the MYCG (magenta, yellow, cyan, and green) CCD imager data and converts it to the industry standard 4:2:2 component digital video in YCrCb format. The component digital video can be used directly or after processing by the video encoder, the composite output formats can be used. The camera uses a +5 V supply in the form of a wall plug-in unit.
I2C Control and Settings
The camera incorporates an I2C EEPROM, which provides all necessary register settings for the camera on power-up. This EEPROM can be programmed using either the digital video connector HDR1 (Figure 7), HDR4 (Figure 6) or the I2C external connector HDR2 (Figure 1). Only one of these approaches should be used at a time. The camera must be re-powered, or the CS7666 must be reset, for these new EEPROM settings to take effect. Additionally, all registers are accessible using the I2C control channel, and the Crystal software is compatible with both connection schemes.
Power Requirements
The camera requires a reasonably filtered (less than 200 mV ripple) +5 V power supply feed, which is used by the processor board and the encoder board. A charge pump is used to generate both +15 V and -8 V required by the CCD imager.
Figure 1. External I2C Connector.
Analog Processor
The CCD output is connected to the CS7615 analog processor chip (see Figure 4). The CS7615 performs all necessary analog processing, including Correlated-Double-Sampler (CDS), AutomaticGain-Control (AGC), Black level adjust, and appropriate output data formatting to allow the mosaic (MYCG) CCD imager data to be processed by the CS7666 digital processor. The CS7615 control registers are accessible via the I2C control bus.
Multiple Configurations
Switch S1 is used to select between several preprogrammed configurations. The CRD7666-7C is preconfigured for 720x480 NTSC (S1 = 100x). the Pal version, CRD7666-7CP, is preconfigured for 720x576 (S1 = 010x). When shipped as part of the CRD7615-8P PCI kit, S1 = 000x and the camera provides 640x480 digital video only.

Digital Processor
The CS7666 digital processor is included on the CCD+Video processor (see Figure 6). The CS7666 converts the digital mosaic data from the CS7615, into 4:2:2 component digital video that adheres to the ITU H.656 transport protocol. The AutomaticWhite-Balance and other control registers are accessible via the main I2C interface.
Figure 2. S1
Digital Output Options
The camera has a 15-pin PCMCIA style connector which connects via a cable to a PCI card (Figure 7) and provides a simple means of integrating the camera's digital output into a PC.

Composite Output Options
The CRD7615-7A and -7C provide two analog output mode connectors for composite and S-Video. The Composite output is available in connector J1, while the S-Video is available in connector P1 (Figure 9). the video processor board and the associated encoder board carries all necessary signals. The supported camera mounts are available from Marshall and can be used for both simple 12mmx0.5 lenses as well as standard C-Mount lenses.
Schematics and Gerber Files
The CRD7666-7C schematics and PCB layout files are available upon request in Zuken-Radac file format. The PCB Gerber files are also available upon request.
VIDEO ENCODER BOARD
The main digital output connector (Figure 7) provides industry standard H.656 compliant component digital video output from the CCD board to the vdeo encoder board. The video encoder (Figure 9) provides both composite and S-Video output via connectors J1 and P1. The board-to-board connector (Figure 6) routes all necessary signals to the upper half of the camera.
SPECIAL NOTES
1) The camera power supply can be configured to receive power from an external power module or from the digital video connector.
CCD+VIDEO PROCESSOR BOARD
The CCD imager and Video processor board of the camera includes a Panasonic MN3711OFP CCD imager and a Panasonic MN3113F vertical driver (with integrated charge pump). (Figure 5). Additionally, the CS7615 Analog Processor (Figure 4) is also inlcuded. The CS7666 Digital Video Processor carries out all color space processing as well as standard image processing (see CS7666 data sheet for further details). A connector (Figure 3) between
