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 75

Ω 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 75

Ω 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.
