OV7620/OV7120 Product Specifications - Rev. 1.2 (7/10/01)
0.4 ZV Port Interlace Timing
The ZV Port is a single-source uni-directional video bus between a PC Card socket and a VGA
controller. The ZV Port complies with CCIR601 timing to allow NTSC decoders to deliver real-
time digital video straight into the VGA frame buffer from a PC Card. OV7620/OV7120 support
ZV Port Timing, which output signal can be output to a PC Card directly, then to VGA controller.
The timing is as below:
Notes: ZV Port format output signal include:
All Timing Parameters is list in following table.‘
VSYNC: Vertical sync pulse.
HREF: Horizontal valid data output window.
PCLK: Pixel clock used to clock valid data and CHSYNC into ZV Port. Default frequency is 13.5MHz when
Y<7:0>: 8 Bit luminance data bus..
UV<7:0>: 8 Bit chrominance data bus.
use 27MHz as system clock. Rising edge of PCLK is used to clock the 16 Bit data.
