CY800 CY800 300M-450MHz RF receiver   General Description The CY800 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 CY800, which eliminates manual tuning and reduces production costs. All IF filtering and post-detection (demodulator) data filtering is provided within the CY800, 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 CY800 offer two modes of operation; fixed-mode (FIX) and sweep-mode (SWP). In fixed mode the CY801 functions as a conventional super-heterodyne receiver. In sweep mode the CY800 sweeps a wider RF spectrum. Fixed-mode provides better selectivity and sensitivity performance and sweep mode enables the CY800 to be used with low cost, imprecise transmitters.   Features Frequency from 300MHz to 440MHz Voltage: 3.3V-5.5V Sensitivity: –106 dBm sensitivity, 1kbps and BER 10E-02 Data-rate up to 8kbps (fixed-mode) Low Power Consumption ■ 2.7mA fully operational (315MHz) 3.7mA fully operational (433MHz) ■ 0.9μA in shutdown ■250μA in polled operation (10:1 duty-cycle) Very low RF re-radiation at the antenna Highly integrated with extremely low external part count   Package Information: (unit: mm) CY800     Ordering Information
