1 / 21 page ![]() TH72032 868/915MHz ASK Transmitter Page 1 of 21 REVISION 012 - JUNE 14, 2017 3901072032 Features Fully integrated PLL-stabilized VCO Frequency range from 850 MHz to 930 MHz Single-ended RF output ASK achieved by on/off keying of internal power amplifier up to 40 kbit/s Wide power supply range from 1.95 V to 5.5 V Very low standby current On-chip low voltage detector High over-all frequency accuracy Adjustable output power range from -12 dBm to +9.5 dBm Adjustable current consumption from 5.1 mA to 13.4 mA Conforms to EN 300 220 and similar standards 8-pin Small Outline Integrated Circuit (SOIC) Application Examples General digital data transmission Tire Pressure Monitoring System (TPMS) Remote Keyless Entry (RKE) Low-power telemetry Alarm and security systems Garage door openers Home automation Pin Description Ordering information Product Code Temperature Code Package Code Option Code Packing Form Code TH72032 K DC BAA-000 RE TH72032 K DC BAA-000 TU Legend: Temperature Code: K for Temperature Range -40°C to 125°C Package Code: DC for SOIC Packing Form: RE for Reel, TU for Tube Ordering example: TH72032KDC-BAA-000-TU General Description The TH72032 ASK transmitter IC is designed for applications in the European 868 MHz industrial-scientific-medical (ISM) band, according to the EN 300 220 telecommunications standard. It can also be used for any other system with carrier frequencies ranging from 850 MHz to 930 MHz (e.g. for applications in the US 915 MHz ISM band). The transmitter's carrier frequency fc is determined by the frequency of the reference crystal fref. The integrated PLL synthesizer ensures that each RF value, ranging from 850 MHz to 930 MHz, can be achieved by using a crystal with a reference frequency according to: fref = fc/N, where N = 32 is the PLL feedback divider ratio. |
