Silicon Labs Si4010 RF Transmitters

Silicon Labs Si4010 Crystal-less SoC RF Transmitters with an integrated 8051 microcontroller is the industry's first single-chip remote control IC. These Silicon Labs transmitters require only one external bypass capacitor, a printed circuit board, a battery, and an external casing with push buttons to form a complete remote control. Based on the proven Si500 silicon oscillator, its patented crystal-less architecture achieves ±150ppm carrier-frequency accuracy over the commercial temperature range and ±250ppm over the industrial temperature range. This architecture is twice as accurate as traditional low-cost SAW-based transmitters with no external crystal. The device operates over a continuous frequency range of 27 to 960MHz and includes a programmable Power Amplifier (PA) with output powers of up to +10dBm. It also includes automatic antenna tuning and PA edge-rate control to comply with FCC, ETSI, and ARIB radio frequency regulations.
