AEL Crystals has announced that its devices have been approved for use with a wide range of Remote Keyless Entry (RKE) chipsets supplied by Infineon from its wireless control product portfolio.
The company’s devices recommended for use with this range of chipsets include 15 transmitter and 15 receiver crystal oscillators covering the 315, 434.2, 868, 868.4 and 915MHz frequency bands, together with five variants for transceivers covering the 315, 434.15, 868.3 and 915MHz frequency bands.
These devices offer an adjustment tolerance of +/-10ppm, and a frequency stability of +/-20ppm across the temperature range, -40 to 85oC. Ageing effects are between 10 and 15ppm over a ten year span.
Remote Keyless Entry is widely used in modern cars. A variety of key fob designs are possible based on Infineon’s highly integrated SmartLEWIS MCU family, which combines the transmitter and the micro-controller on one single chip.
