CY807/808 Datasheet 450M-1000MHz Receiver CY807/808 DESCRIPTION The CY807/808 is a UHF ASK receiver IC which operates 3.6V-5.5V, from 450MHz to 1000MHz with typical receiving sensitivity of -107d Bm. The CY807/808 is a super-heterodyne receiver for ASK and OOK modulation such as pulse width modulation, variable pulse modulation, Manchester modulation and so on. The down-conversion mixer also provides image rejection function to remove the image band and selects the desired signal. 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. CY807 is the SSOP16 package version. CY808 is the SOP16 package version.
