NCK2983AHN/T2CY

The NCK2983 device is a radio frequency transceiver with embedded microcontroller intended for use in an Automotive environment. All functions including customer programmable non-volatile program memory are included in a single package. The device is suitable for use in both Car Keyfob & Body Control Module type applications. NCK2983 includes an embedded microcontroller to allow complete subsystem functions to be implemented. All device functions, including some customer programmable non-volatile memory are included in a single CMOS die. NCK2983 is able to simultaneously receive three separate channels, where the maximum separation between the two outer band edges of the selected channels does not exceed 1.8 MHz. The Transmitter has a high dynamic range ( -25 dBm to +12 dBm ), and efficient power ramping power amplifier. The Phase Noise of the transmitter conforms to the ARIB standard. The transceiver is configured to operate with low active and standby power, ideal for battery powered applications. The polling mode, controlled by the internal microcontroller, may be configured by the user.
