Product Overview

SII9125CTU is a dual-input HDMI 1.3 receiver IC from Silicon Image (Lattice). Built with a 2:1 HDMI mux, it supports 1080p deep color, integrated HDCP decryption, I2S/SPDIF audio output. It delivers stable low-power video & audio decoding for AV equipment, digital TVs and professional AV matrix.

Core Advantages

Built-in 2:1 HDMI Input Mux

Seamlessly switch between two HDMI sources, reduce peripheral components and simplify PCB wiring.

Multi-Channel Audio Processing

Extract uncompressed HD audio from HDMI, output via I2S or SPDIF to connect DSP and audio amplifiers directly.

Adaptive Cable Equalization

Compensate signal attenuation, jitter and skew from long HDMI cables to guarantee stable transmission.

Factory Preloaded HDCP Keys

Built-in HDCP decryption engine with pre-programmed keys, no extra key storage circuit required.

Frequently Asked Questions

Q1: Is SII9125CTU 100% original genuine?

A: Yes. All SII9125CTU are brand new original chips from Silicon Image / Lattice. Every batch will be inspected strictly. We ship components in original ESD trays to protect 100-pin TQFP pins from damage and moisture.

Q2: Can 2 HDMI input ports work simultaneously?

A: No. This IC integrates a built-in 2:1 multiplexer. Two HDMI sources can be connected at the same time, but only one channel works for decoding. Source switching is controlled by I2C firmware commands.

Q3: What does CTU in SII9125CTU stand for?

A: C = Commercial temperature grade (0℃ ~ +70℃). TU = Lead-free RoHS 144-pin TQFP packaging, designed for SMT production lines.

Q4: How to get datasheet, register guide and bulk price?

A: Fill in the Quick Inquiry form on this page, leave your project info and order quantity. Our technical team will send datasheets, code snippets and tiered quotations within 24 hours.

Q5: What is the delivery time for SII9125CTU?

A: Stock items can be shipped within 1-2 working days. Global delivery takes 3-7 days via DHL/FedEx/UPS.

Q6: Can I get free samples for testing?

A: Yes, sample orders are supported. Submit your sample demand via inquiry form, we will confirm sample cost and freight for you.
