GENERAL DESCRIPTION

The ECF800 is a 315Mhz/433.92MHz low-IF RF receiver with automatic gain control and OOK/ASK

demodulator. The ECF800 requires few external components and makes it ideal for cost-sensitive

applications.

The low-noise amplifier (LNA), phase-lock loop (PLL), mixer, IF filter, received-signal strength indicator

(RSSI), and baseband section are included all on-chip. The low-drop output (LDO) regulators are also

on-chip which can allow 3V to 5.5V power supply range and consumes 10mA of supply current, especially

of operation is allowed -40℃ to 125℃

wide Temperature Range. The ECF800 achieves -110dBm

sensitivity at a data rate of 2Kbps and -25dBm maximum allowed input power.

ECF800

is designed as Receiver SOC for remote controller in home-use consumer product, usually

applied to LED lighting control, smart Switch and Fan control systems.

E-CMOS’s advance technology delivers small, reliable, very low power consumption, green and

cost-effective keyboard remote control system solution. This

provides a green solution to environment

pollution and global warming and let your company become a green solution provider.
