RCS-S09U Universal ISM Band FSK Transceiver Module

Our wireless energy saving monitor and control system as well as our tire-pressure monitoring system (TPMS) adopts our own transceiver modules. That's why our products are so competitive in the market. If you are looking for a RF Transceiver Module developer and supplier for your project, we are the right choice to provide personalized service and solution for you.

Our RCS-S09U is a compact and low cost FSK wireless transceiver module based on ISM band. Its core circuit adopts RF transceiver chips of the unique PLL technology. It works with frequency of 433MHz bands, complying with FCC and ETSI regulations. The module provides an SPI interface so that the MCU can conveniently realize the parameter settings and other functions via software.

This module is integrated with all RF related functions and parts. By providing several simple digital I/O interfaces, the module makes it possible for users with very little knowledge of radio-technology to easily develop stable and reliable wireless products.

Highlights of RF transceiver module RCS-S09U:
	Low cost with high performance/price ratio
	To tune freely during production
	Based on PLL and zero IF technologies
	Quick PLL lock speed
	High resolution PLL with 2.5KHz step
	High data rate up to 115.2kbps with internal demodulator. The highest data rate can reach 256kbps with external RC filter
	Differential antenna input/output
	Automatic antenna tuning
	Programmable TX frequency deviation from 15 to 240 KHz
	Programmable receiver bandwidth from 67 to 400 KHz
	Analog and digital signal strength indicator (ARSSI/DRSSI)
	Automatic frequency control (AFC)
	Data quality detection (DQD)
	Internal data filtering and clock recovery
	RX synchron pattern recognition
	SPI compatible serial control interface
	Clock and reset signal output for external MCU operation
	16 bit RX Data FIFO
	Two 8 bit TX data registers
	Standard 10MHz crystal reference
	Wake-up timer
	2.2V-3.8V power supply
	Low power consumption
	Standby current less than 0.3uA
	Support very short packets down to 3 bytes
