• Manufacturer: AKM Semiconductor, Inc.

(5) RGB 18bit Data Input Format (RGB 6:6:6 ）
Output signal is set CONVMOD[1:0]-bit of I/O Data Format Register (R/W) [Sub Address 0x0B] and HD Mode Register
(R/W) [Sub Address 0x00] or SD Block Control Register (R/W) [Sub Address 0x11]
Rev-E-00
The Register setting is defined as following table.
[I/O Data Fromat Register] Setting
(5-1) 525i / 625i data input case
(5-2) 525P / 625P data input case
In case of encoding NTSC/PAL / 525i/625i , 525p/625p component signal, Clock rate to CLKIN pin 27MHz..
Using as High Speed DAC mode, the maximum conversion rate is 54MHz.
DATA17 - DATA0 pins are used as Data Input pins.
