Universal ISM Band FSK Receiver RF01

DESCRIPTION:

RF01

Hope’s RF01 is a single chip, low power, multi-channel

FSK receiver designed for use in applications requiring

FCC or ETSI conformance for unlicensed use in the 315,

433, 868, and 915 MHz bands. Used in conjunction with

Hope's FSK transmitters, the RF01 is a flexible, low cost,

and highly integrated solution that does not require

production alignments. All required RF functions are

integrated. Only an external crystal and bypass filtering are

needed for operation.

The RF01 has a completely integrated PLL for easy RF design, and its rapid settling time allows for

fast frequency hopping, bypassing multi-path fading, and interference to achieve robust wireless links.

The PLL’s high resolution allows the usage of multiple channels in any of the bands. The baseband

bandwidth (BW) is programmable to accommodate various deviation, data rate, and crystal tolerance

requirements. The receiver employs the Zero-IF approach with I/Q demodulation, therefore no external

components (except crystal and decoupling) are needed in a typical application. The RF01 is a complete

analog RF and baseband receiver including a multi-band PLL synthesizer with an LNA, I/Q down

converter mixers, baseband filters and amplifiers, and I/Q demodulator.

The chip dramatically reduces the load on the microcontroller with integrated digital data processing:

data filtering, clock recovery, data pattern recognition and integrated FIFO. The automatic frequency

control (AFC) feature allows using a low accuracy (low cost) crystal. To minimize the system cost, the

chip can provide a clock signal for the microcontroller, avoiding the need for two crystals.

For low power applications, the device supports low duty-cycle operation based on the internal

wake-up timer.
