CMOS LSI
TV Image Viewer LSI
Overview
This LSI is TV image viewer. A 16Mbit SDRAM is built-in as image frame buffers, on which an external CPU is
able to draw the images, then another part of this LSI displays the SDRAM images on TV in NTSC/PAL after video
data encoding. This LSI equips H/V scaling circuit to scale up QVGA size image to VGA to display on the TV screen,
for instance.
The main features of this LSI are specified as below.
Features
• NTSC/PAL video encoder is integrated.
Various format support
ITU-R601 (13.5MHz/NTSC&PAL) SQ (12.27MHz/NTSC, 14.75MHz/PAL)
NTSC-J, M/PAL-B, D, G, H, I/PAL-M, N
Various image adjustment
Y signal: brightness and contrast adjustment
C signal:U gain, V gain, HUE and Burst amplitude adjustment
Trap filter
Trap filters locate on the Y signal pass to reduce cross color interference. The trap strength is adjustable by
register setup.
Built-in color bar
This is for system test and level adjustment.
10 bit DAC with 75Ω driver
A high accuracy video DAC of 10bit is built-in. Its DAC output is able to be connected to TV input or any
image devices, thanks for its 75Ω driver built-in.
• It mounts 16Mbit SDRAM to store multiple VGA size images. Since it has the arbitration function built-in, the
access timing from CPU for drawing can be used without any care of real-time access condition for TV display.
VGA 30fps performance can be achieved with appropriate setting of system clock, the burst size of SDRAM,
scaling ratio etc.
