KT0803L pinout datasheet


KT0803L, our new generation of low cost Monolithic Digital FM Transmitter, is designed to process high-fidelity stereo audio signal and transmit modulated FM signal over a short range. It’s based on the architecture of awardwinning KT0801 and it’s also an upgrade of KT0803K and KT0803M. The additional features added to KT0803L are standby mode through software, ALC(automatic level control), multiple reference clock, increased SNR performance and frequency response.

The KT0803L features dual 20-bit ΔΣ audio ADCs, a highfidelity digital stereo audio processor and a fully integrated radio frequency (RF) transmitter. An on-chip low-drop-out regulator (LDO) allows the chip to be integrated in a wide range of low-voltage battery-operated systems with power supply ranging from 1.6V to 3.6V. […]

A digital stereo FM transmitter is a device that allows you to broadcast an audio signal wirelessly over FM radio frequencies in stereo format. It typically takes an audio input, digitizes it, and modulates it onto an FM carrier signal for transmission.

Digital stereo FM transmitters are commonly used for a variety of applications, including personal broadcasting, drive-in theaters, community radio stations, wireless audio transmission in events or conferences, and in-car entertainment systems. They provide a convenient way to transmit high-quality stereo audio wirelessly to FM radio receivers.



1. Automatic power down power amplifier when silence is detected

2. Multiple reference clock support including from 32.768KHz to 26MHz

3. ALC (Automatic Level Control)

SiL9024A Datasheet PDF – HDMI Transmitter – Silicon Image

Partnumber : SiL9024A

Function: HDMI transmitter supports the High Definition Multimedia Interface

Package: 81-ball, 49-ball VFBGA, 72-pin QFN Type

Manufacturer: Silicon Image


SiL9024A HDMI Transmitter


The SiI9022A / SiL9024A HDMI transmitter supports the High Definition Multimedia Interface (HDMI) Specification on a wide range of mobile products. High definition camcorders, digital still cameras, and personal mobile devices connect directly to a large installed base of HDMI TVs and DVI PC monitors by using the flexible audio and video interfaces provided by this ultra-low-power solution. S/PDIF or I2S inputs enable a pure digital audio connection to virtually any system audio processor or codec. This transmitter is the next generation of its family and is an enhanced replacement for the SiI9022/SiI9024 device, with lower power and enhanced features.

The SIL9024A transmitter is pre-programmed with HDCP keys and has completely self-sequencing HDCP detection and authentication, including SHA-1 for repeaters. The device supports High-bandwidth Digital Content Protection (HDCP) for devices that require secure content delivery.

Control Capability

1. Consumer Electronics Control (CEC) interface incorporates an HDMI-compliant CEC I/O with hardware protocol and arbitration logic, and requires no external calibration

2. Monitor detection is supported through both Hot Plug and Receiver Sense circuits

3. Single slave I2C from host, passing through to master I2C interface for DDC connection, simplifies board layout and lowers cost

4. Defaults to SiI9020 transmitter register-compatible mode for operation with existing legacy software
