MICRF009 QwikRadio Low-Power UHF Receiver Insert as inline graphic General Description QwikRadio The MICRF009 is a single chip, ASK/OOK (ON-OFF Features Keyed) RF receiver IC. It provides the same function but High sensitivity (104dBm) with performance enhancements over earlier QwikRadio Fast recovery from shutdown (1ms) receivers. Two key improvements are: higher sensitivity 300MHz to 440MHz frequency range (typically 6dB higher than the MICRF002) and faster Data-rate up to 2.0kbps (fixed-mode, Manchester encoding) recovery from shutdown (typically 1ms). Just like all other Low power consumption members of the QwikRadio family, the MICRF009 2.9mA fully operational (315MHz) achieves low power operation, a very high level of 0.15A in shutdown integration, and it is particularly easy to use. 290A in polled mode (10:1 duty-cycle) All post-detection (demodulator) data filtering is provided Shutdown input on the MICRF009, so no external baseband filters are Automatic tuning, no manual adjustment required. One of two filter bandwidths may be selected Very low RF re-radiation at the antenna externally by the user. The user only needs to program the Highly integrated with extremely low external part count appropriate filter selection based on the data rate and code 1ms time to good data modulation format. The MICRF009 offer two modes of operation fixed-mode Applications (FIX) and sweep-mode (SWP). In fixed-mode the MICRF009 functions as a conventional superheterodyne Automotive remote keyless entry (RKE) receiver. In sweep-mode the MICRF009 employs a Long range RF identification patented sweeping function to sweep a wider RF spectrum. Remote fan and light control Fixed-mode provides better selectivity and sensitivity Garage door and gate openers performance while sweep mode enables the MICRF009 to be used with low-cost, imprecise transmitters.

Nominal Demodulator Filter Bandwidth vs. SEL0, Operating Mode at 433.92 MHz Note: SEL0 must connect to VDD = 1 or VSS = 0. Do not float SEL0 Standard 16-Pin SOIC (M) Pin Description Pin Number Pin Name Pin Function 1 SEL0 Bandwidth Selection Bit 0 (Input): Configure to set the desired demodulator filter bandwidth. See Table 1. 0 = VSS, 1 = VDD, don not float SEL0 2, 3 VSSRF RF Analog Return (Input): Ground return to the RF section power supply. See Applications Information for bypass capacitor details. 4 ANT Antenna (Input): See Applications Information for information on input impedance. For optimal performance the antenna impedance should be matched to the antenna pin impedance. 5 VDDRF RF Analog Supply (Input): Positive supply input for the RF section of the IC. VDDBB and VDDRF should be connected together directly at the IC pins. 6 VDDBB Baseband Digital Supply (Input): Positive supply input for the baseband section of the IC. VDDBB and VDDRF should be connected together at the IC pins. 7 CTH Data Slicing Threshold Capacitor (External Component): Capacitor extracts the DC average value from the demodulated waveform, which becomes the reference for the internal data slicing comparator. See Applications Information for selection. 8 NC No connect. 9 VSSBB Baseband Digital Return (Input): Ground return to the baseband section power supply. See Applications Information for bypass capacitor and layout details. 10 DO Digital Output (Output): CMOS level compatible data output signal. 11 SHUT Shutdown (Input): Shutdown-mode logic-level control input. Pull low to enable the receiver. This input has an internal pulled-up to VDDRF. 12 CAGC AGC Capacitor (External Component): Integrating capacitor for on-chip AGC (automatic gain control). See Applications Information for capacitor selection. 13 SEL1 Bandwidth Selection Bit 1 (Input): Must tie to ground. Reserved for future use. 14 REFOSC2 Reference Oscillator (External Component or Input): Timing reference for on-chip tuning and alignment. 15 REFOSC1 Reference Oscillator (External Component or Input): Timing reference for on-chip tuning and alignment. 16 SWEN Sweep-Mode Enable (Input): Sweep- or fixed-mode operation control input. When SWEN is high, the MICRF009 is in sweep mode when SWEN is low, the receiver operates as a conventional single- conversion superheterodyne receiver. This pin is internally pulled-up to VDDRF.
