Cy521 Wireless Receiver Module IC Chip

DESCRIPTION:
The CY521 is a general purpose, 2.2V-3.6V ASK Receiver that operates at 300-450MHz with typical sensitivity of -109dBm.  

The CY521 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 CY521. Any one-of-four filter bandwidths may be selected externally by the user in binary steps, from 1.25 KHz to 10 KHz. 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.

CY521 is the SOP8 package version.
