1. General information
1.1 General description
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 micro-controller memory interface (DMA)
allowing the micro-controller to complete the data handling and handshaking.
The device has an embedded RISC micro-controller 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 -35dBm to +14dBm
which makes it ideal for the use in narrow band 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
micro-controller. The device can be interfaced via SPI, UART or LIN protocol compatible
UART. Simplified programming of the device is facilitated by the HAL (Hardware
Abstraction Layer).
The transceiver is configured to operate with low active and standby power consumption,
ideal for battery powered applications.
