BU9969KN-E2

Overview

The BU9969KN-E2 is a digital video encoder IC designed for NTSC and PAL standards, supporting ITU-R BT.601 and BT.656 protocols. It converts captured images into composite signals viewable on TV monitors. The device accepts YCbCr 4:2:2 data in 8-bit (656 mode) or 16-bit (601 mode), as well as RGB 5:6:5 formats. Key electrical parameters include DVDD/PVDD at 1.8V ±0.1V and IOVDD/AVDD at 3.0V ±0.3V. System clock frequencies are 27MHz for 656 mode and 13.5MHz for 601 mode. It features a 10-bit video DAC with full-scale voltage of 1.25V typ., integral linearity error of ±8.0 LSB typ., and differential linearity error of ±1.0 LSB typ. Operating temperature range is -20°C to 70°C.

Feature Summary

• Supports NTSC-M and PAL-B/D/G/H/I video formats with built-in trap filter and x4 system clock over-sampling function.
• Accepts multiple input data formats including YCbCr 4:2:2 via 656 or 601 modes, and RGB 5:6:5 in 601 mode.
• Integrates a 10-bit video DAC, PLL, and gamma correction circuitry for high-quality signal processing.
• Utilizes a 2-wire serial interface for configuration and control.

Applications

• Cell phones
• Mobile devices requiring image viewing on TV monitors

Procurement Notes

Verify the specific ordering suffix E2 corresponds to the embossed tape and reel packaging format containing 2500 units per reel. Confirm that the VQFN36 package dimensions align with the target PCB footprint requirements. Ensure compatibility with the required supply voltages of 1.8V for digital core and 3.0V for I/O and analog sections during design validation.

Selection Notes

Select this component when a compact digital video encoder is needed for mobile applications supporting standard definition television outputs. Consider the dual-voltage requirement (1.8V and 3.0V) and the availability of both 656 and 601 input interfaces. Evaluate the need for the integrated 10-bit DAC and trap filter against external component alternatives to optimize board space and power consumption.

Part Context

The BU9969KN-E2 belongs to ROHM's Digital Video Encoders series, specifically engineered for mobile and portable electronics. It facilitates the conversion of digital image data into analog composite video signals compliant with NTSC and PAL standards. The device integrates essential signal processing blocks such as a PLL, DAC, and gamma correction within a small VQFN36 package, targeting space-constrained designs like cell phones.
