Product Description

CY801 300M-450MHz ASK Receiver IC for 433 module

DESCRIPTION:
The CY801 is a single chip ASK/OOK (ON-OFF Keyed) RF receiver IC. This device is a true "antenna-in to data-out" monolithic device. All RF and IF tuning are accomplished automatically within its side, which eliminates manual tuning and reduces production cost. All IF filtering and post-detection (demodulator) data filtering is provided within the IC side, so no external filters are necessary. One of four demodulator filter bandwidths may be selected externally by the user. The result is a highly reliable yet low cost solution. The device with a set of easily determined values based upon data rate, code modulation format, and desired duty-cycle operation.
The CY801 offer two modes of operation: fixed-mode (FIX) and sweep-mode (SWP). In fixed mode its function as a conventional super-heterodyne receiver. In sweep mode the CY801 sweeps a wider RF spectrum. Fixed-mode provides better selectivity and sensitivity performance and sweep mode enables the CY801 to be used with low cost, imprecise transmitters.
