PI5V330
12.18.
General Description
12.18.1.
The PI5V330 is well suited for video applications when switching composite or RGB analog. A picture-
in-picture application will be described in this brief. The pixel-rate creates video overlays so two or more
pictures can be viewed at the same time. An inexpensive NTSC titler can be implemented by
superimposing the output of a character generator on a standard composite video background.
MST9883
12.19.
12.19.1. General Description
The MST9883C is a fully integrated analog interface for digitizing high-resolution RGB graphics signals
from PC's and workstations. With a sampling rate capability of up to 140 MHz, it can accurately support
display resolutions up to 1280x1024 (SXGA) at 75 Hz. The clamped input circuits provide sufficient
bandwidth to accurately digitize each pixel.
12.19.2. Features
• Triple ADC with 12 - 140 MHz Sampling Rate
• Integrated line locked PLL generates pixel clock from HSYNC
• Integrated clamp with timing generator
• Integrated Brightness & Contrast controls
• Pin Compatible with AD9883A
• 4:2:2 and 4:4:4 Output Format Mode
• BT656 output format mode*
• Black and mid-level precision clamp and calibration
