Rutronik adds wireless control receivers from Infineon
August 26, 2010 // Phil Ling
Three wireless control receivers offer high sensitivity and low power consumption.
The TDA5240, TDA5235 and TDA5225 devices provide multi-band support (315MHz, 434MHz, 868MHz and 915MHz) for worldwide coverage and target various automotive applications, including Remote Keyless Entry (RKE) systems, Tire Pressure Monitoring Systems (TPMS), remote start, control, status and alarm functions. In addition, industrial and consumer systems will benefit from the high-integrated wireless control devices. The new receivers are available at distributor Rutronik now.
The TDA5240, TDA5235 and TDA5225 are successors to the TDA5230/31 receiver family. Two of the devices include the powerful digital data processing
introduced with the TDA5230/31, with overall performance and feature set enhancements. Functionalities like IF filter (optional usage of external
filter is possible) and level shifters are now integrated.
Only a few external components are needed which leads to reduced BOM. An innovative integrated Low Noise Amplifier (LNA) concept provides the system developers with enhanced design alternatives. Depending on the application needs this LNA can extend the system range or eliminate the need for an external LNA to reduce system complexity and costs.
High sensitivity of the new family (typically -119dBm for FSK and typically -116dBm for ASK) is due to improved digital signal processing.The TDA5240/35/25 devices provide a data rate with several embedded encodings and modulation schemes specified at up to 112kchip/s (FSK). System designers can use the multi-band, multi-channel receivers for systems operating at frequency bands 315/434/868/915MHz, with one crystal for all supported frequency bands.
A high-resolution sigma- delta fractional-N PLL synthesizer provides a fine multi-channel resolution of 10.5Hz. Multi-protocol handling enables flexible designs based on one platform. The receivers are able to handle data from both RKE and TPMS transmitters, even when they have different modulation, bit rate, and data format. Therefore only one device can be used for multiple applications (RKE, TPMS, remote start, etc.) where today there is the need for two.
