1 / 27 page Specifications of any and all SANYO Semiconductor Co.,Ltd. products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer 's products or equipment. To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer 's products or equipment. Any and all SANYO Semiconductor Co.,Ltd. products described or contained herein are, with regard to "standard application", intended for the use as general electronics equipment. The products mentioned herein shall not be intended for use for any "special application" (medical equipment whose purpose is to sustain life, aerospace instrument, nuclear control device, burning appliances, transportation machine, traffic signal system, safety equipment etc.) that shall require extremely high level of reliability and can directly threaten human lives in case of failure or malfunction of the product or may cause harm to human bodies, nor shall they grant any guarantee thereof. If you should intend to use our products for new introduction or other application different from current conditions on the usage of automotive device, communication device, office equipment, industrial equipment etc. , please consult with us about usage condition (temperature, operation time etc.) prior to the intended use. If there is no consultation or inquiry before the intended use, our customer shall be solely responsible for the use. O1012HKPC 20101028-S00001 No.A2131-1/27 Ver.1.07 * I 2C Bus is a trademark of Philips Corporation. LC822973 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. Continued to the next page.
