SI4012-C1001GTR Description

Short technical summary and product information.

The Silicon Labs SI4012-C1001GTR is a fully-integrated, crystal-less CMOS RF transmitter designed for the sub-GHz ISM band. It is optimized for battery-powered applications requiring low standby currents and high output transmit power.

 

This device offers continuous frequency coverage from 27 to 960 MHz, with an adjustable output power range from -13 dBm to +10 dBm. It supports data rates up to 100 kbaud in FSK mode and 50 kbaud in OOK mode, utilizing FSK and OOK modulation.

 

The Si4012 operates from a power supply of 1.8 V to 3.6 V and features low power consumption, drawing 14.2 mA in OOK mode and 19.8 mA in FSK mode at +10 dBm output power. It includes features such as automatic antenna tuning, programmable ramp rate, an integrated voltage regulator, a 255-byte FIFO, and a low battery detector.

 

Packaged in a 10-MSOP, this surface-mount component is suitable for various applications including home automation, remote sensing, and remote keyless entry (RKE). It operates within a temperature range of -40°C to +85°C.
