To Overcome issues commonly found with traditional RF transmitters
Although SAW-based transmitters are widely used in remote controls because of their low component costs, there are many disadvantages with this old technology. Besides the high system cost from the large number of RF BOM components, SAW-based transmitters also suffer from poor carrier frequency accuracy, single frequency operation, OOK only modulation, inconsistent performance, sensitivity to component tolerances and low manufacturing yield.
In contrast, the Si4010 transmitter is a complete system-on-chip (SoC) remote control IC. Based on the proven Si500 silicon oscillator, its patented crystal-less architecture achieves ±150 ppm carrier frequency accuracy over the commercial temperature range and ±250 ppm over the industrial temperature range, which 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 960 MHz and includes a programmable power amplifier (PA) with output powers of up to +10 dBm, automatic antenna tuning and PA edge rate control to comply with FCC, ETSI and ARIB radio frequency regulations. The embedded 8051 MCU is instruction-optimized for fast throughput and comes with 512 bytes of internal data RAM, 4 kB of RAM, 8 kB of OTP NVM, 128 bits of EEPROM, a 12 kB library of ROM functions and a hardware-accelerated 128 bit AES encryption algorithm.
Ultra-low-power (10 nA) and wake-on-touch operation make the Si4010 ideal for coin-cell battery applications.

Designing a remote control using the Si4010 overcomes many issues commonly found with traditional RF transmitters. The Si4010 removes the difficult and tedious RF matching problem with its antenna tuning feature, which reduces expensive RF design time and improves time-to-market. The hardware task comes down to choosing the best PCB antenna for the given remote control geometry and laying out the pads and connections for the Si4010, the PCB trace antenna, a bypass capacitor, buttons and the battery.
