CY803/802 Datasheet
300M-450MHz RF receiver
General Description
The CY803/802 is a general purpose, 3.3-5V, super-heterodyne Receiver that operates from 300M to 450MHz with typical sensitivity of -110dBm. The CY803/802 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 CY803/802. 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.
