AK8113

Overview

The AK8113 is a digital video encoder manufactured by Asahi Kasei Microdevices (AKM). It functions as an NTSC/PAL digital video encoder designed for set-top boxes and digital televisions. The device converts ITU-R BT.601/656 standard 8-bit parallel data into analog composite video signals and S-video outputs in both NTSC and PAL formats. Key technical features include support for copy protection, closed captioning, Video Blanking ID (CGMS-A), and Wide Screen Signaling (WSS). These functions are managed via a high-speed I2C bus interface operating at 400kHz. The component operates on a single 2.8V to 3.3V CMOS supply and utilizes a 48-pin LQFP or 57-pin FBGA package.

Feature Summary

• NTSC-M and PAL-B/D/G/H/I/M/N encoding capabilities
• Simultaneous composite video and S-video signal outputs
• ITU-R BT.656 4:2:2 8-bit parallel input with EAV decoding
• Integrated Closed Caption encoding and Macrovision Copy Protection Rev. 7.1

Applications

• Set-top boxes (STB)
• Digital television systems
• Video encoding modules requiring CGMS-A and WSS support

Part Context

The AK8113 belongs to the AK881x series of low-voltage, low-power digital video encoders produced by Asahi Kasei Microsystems. This family includes related models such as the AK8811, AK8812, AK8814, AK8815, and AK8816VG. These components share similar architectures for converting digital video standards to analog outputs, targeting consumer electronics applications like STBs and digital TVs.
