Product Description

CY803 300M-450MHz RF receiver ic

DESCRIPTION:
The CY803 is a general purpose, 3.3-5V ASK Receiver that operates from 300M to 450MHz with typical sensitivity of -109dBm. The CY803 functions as a super-heterodyne receiver for OOK and ASK modulation up to 10kbps. The down-conversion mixer also provides image rejection. All post-detection data filtering is provided on the CY803. Any one-of-four filter bandwidths may be selected externally by the user in binary steps, from 1.25kHz to 10kHz. The user need only configure the device with a set of easily determined values, based upon data rate, code modulation format, and desired duty-cycle operation.
