Introduction

The SY88927VKG is an integrated broadcast programmable transmitter system based on the medium power, integrated package. It supports up to 3x3 external transmitter channels, avoiding the need for multiple carrier signals or multiple exciter systems.The driving field of SY88927VKG is related to broadcast system, especially in medium power applications. Its key work principle is based on the synchronous carrier information control. The SY88927VKG can provide the power supply for all external amplifier stages, limiting the number of costly external component parts and simplifying the system architecture for a medium power product, saving cost and size.

Functional Overview

The SY88927VKG includes three external transmitter channels (TXP) with up to 5W peak output power per channel. Each of the TXP channels can operate up to 3x3 stereo mode. It supports up to 32kHz carrier modulation, allowing multiple channels of programming within the same frequency range. The SY88927VKG also includes an integrated quad-band IF receiver with AGC control, providing excellent receive sensitivity comparable to conventional external receiver modules. The SY88927VKG also supports very low external electromagnetic interference (EMI) impact on system application. Its on chip oscillator technology reduces start-up ripple caused by common oscillator signals, and reduces the number of external components required for the system.

The system consists of three user-programmable transmitter channels, a quad-band receive system and an oscillator circuit. The oscillator circuit provides a low-cost, low-EMI solution to generate a synchronized carrier frequency in the system under the command of the onboard microprocessor. The quad-band receive system serves to decode the synchronous carrier signal and decode the program channels. The SY88927VKG is ideal for broadcast systems in medium power applications like TV and FM broadcasting systems, digital audio broadcasting systems and others. It offers flexibility and savings in size, cost and power span due to the advantages of its integrated approach.
