5 / 86 page  Data Sheet 5 2007-02-26 Type Ordering Code Package TDA5252 G2 SP000057332 PG-TSSOP-38 ASK/FSK 915MHz Wireless Transceiver TDA5252 G2 Version 1.1 Product Info General Description The IC is a low power consumption single chip FSK/ASK Transceiver for half duplex low datarate communication in the 915MHz band. The IC offers a very high level of integration and needs only a few external components. It contains a highly efficient power amplifier, a low noise amplifier (LNA) with AGC, a double balanced mixer, a complex direct conversion stage, I/ Q limiters with RSSI generation, an FSK demodulator, a fully integrated VCO and PLL synthesizer, a tuneable crystal oscillator, an onboard data filter, a data comparator (slicer), positive and negative peak detectors, a data rate detection circuit and a 2/3-wire bus interface. Additionally there is a power down feature to save battery power. Features – Low supply current (Is = 9mA typ. receive, Is = 13mA typ. transmit mode) – Supply voltage range 2.1 - 5.5V – Power down mode with very low supply current consumption – FSK and ASK modulation and demodulation capability – Fully integrated VCO and PLL synthesizer and loop filter on-chip with on chip crystal oscillator tuning –I2C/3-wire µController Interface – On-chip low pass channel select filter and data filter with tuneable bandwidth – Data slicer with self-adjusting threshold and 2 peak detectors – FSK sensitivity < -109dBm, ASK sensitivity < -109dBm – Transmit power up to +13dBm – Self-polling logic with ultra fast data rate detection Application – Low Bitrate Communication Systems – Keyless Entry Systems – Remote Control Systems –Alarm Systems – Telemetry Systems – Electronic Metering – Home Automation Systems |
