NXP OL2385AHN/00100Y

The device is a fully integrated single-chip transceiver intended for use in an industrial environment. The device incorporates several commonly used building blocks including a crystal stabilized oscillator, a fractional-N-based phase-locked loop (PLL) for accurate frequency selection in both TX and RX, Low Noise Amplifier (LNA), attenuator for Automatic Gain Control (AGC), I/Q down-mixer and two high-resolution Analog to Digital Converters (ADC). The conversion into the digital domain is done in an early phase, enabling a software defined radio like approach. By transforming signals in the digital domain in an early phase, one highly configurable RX channel is available including channel mixer, channel filter, ASK/FSK demodulator, clock-data recovery, bit processor and a microcontroller memory interface (DMA) allowing the microcontroller to complete the data handling and handshaking. The device has an embedded RiSC microcontroller optimized for high performance and low power as well as an EROM for customer applications. The device also includes a medium power UHF transmit system with a high dynamic range of - 35 to +14 dBm which makes it ideal for the use in narrowband communication systems. The TX system allows transmission with data rates up to 400 kbit/s NRz. Power ramping and splatter avoidance filters are included to ensure that the transmit spectrum fulfills all the common standards in Europe, USA, and Asia. The phase noise of the transmitter supports ARIB operation. The device includes a series of timers to allow for autonomous polling and wake-up applications. The TX and RX data buffers are located in the RAM with autonomous direct memory access (DMA), reducing the 'real-time' overhead for the accompanying microcontroller. The device can be interfaced via SPl, UART, or LIN protocol compatible UART. Simplified programming of the device is facilitated by the HAL (Hardware AbstractionLayer). The transceiver is configured to operate with low active and standby power consumption, ideal for battery powered applications.
