Q: What are the main features of the SII9022ACNU?
A: The SII9022ACNU is a 24-bit RGB input HDMI 1.4a transmitter from Lattice Semiconductor Corporation. It supports HDMI and DVI-compatible video output, with a TMDS core operating up to 165 MHz and video resolutions up to 1080p and UXGA. The device also supports digital audio through I2S and S/PDIF interfaces, includes an integrated color-space converter, and provides I2C control, DDC, hot-plug detection, and power-saving functions. It is supplied in a 72-pin QFN package measuring approximately 10 mm × 10 mm.
Q: What is the SII9022ACNU used for?
A: The SII9022ACNU is used to add HDMI display connectivity to electronic products that generate digital video and audio. Typical applications include digital cameras, camcorders, portable media devices, embedded systems, set-top equipment, and professional video products. It converts the host system's digital video and audio data into an HDMI-compatible output, allowing the equipment to connect to HDMI displays such as monitors and televisions.
Q: Does it have any alternative manufacturer and part number, such as?
A: Possible alternatives depend heavily on the required video resolution, input interface, audio support, package, and software configuration. Within the same Lattice/Silicon Image family, the SII9024ACNU is a closely related option with integrated HDCP support, while SII9022ARBT and SII9022AYBT are package variants of the SII9022A family. Other manufacturers offer HDMI transmitter ICs with similar functions, but they should not be considered drop-in replacements without a detailed hardware and software review. Designers should compare video timing, pixel-clock rate, input bus format, HDMI/DVI compliance, audio interface, power supplies, pinout, and package before selecting a substitute.
Q: Is technical support available for this part?
A: Yes. Technical support can cover datasheet and pinout information, HDMI transmitter configuration, I2C register settings, video and audio interface design, DDC and hot-plug functions, PCB layout, signal integrity, and troubleshooting. Lattice provides technical-support resources for its HDMI transmitter products, including documentation and design assistance. Professional electronic component distributors Nantian can also assist with specification confirmation, sourcing, lifecycle information, and evaluation of alternative devices.
