Product Overview
Description
Product Description
The CY520 is a general purpose, 3.3-5V ASK Receiver that operates from 300M to 450MHz with typical sensitivity of -109dBm.
The CY520 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 CY520. Any one-of-four filter bandwidths may be selected externally by the user in binary steps, from 1.25 kHz 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.
CY520 is the SOP8 package version.

Pin Configuration
| Pin Name | Pin Function |
| RO1 | Reference resonator input connection o Colpitts oscillator stage. May also be driven by external reference signal of 1.5V p-p amplitude maximum. |
| ANT | RF signal input from antenna. Internally AC coupled. It is recommended that a matching network with an inductor-to-RF ground is used to improve ESD protection. |
| VDD | Positive supply connection for all chip functions. |
| VSS | Negative supply connection for all chip functions except RF input. |
| RO2 | Reference resonator input connection to Colpitts oscillator stage, a 18pF capacitor is connected from this pin to GND during normal operation. |
| CAGC | AGC filter capacitor connection. CAGC capacitor, normally greater than 0.47μF, is connected from this pin to GND. |
| CTH | Demodulation threshold voltage integration capacitor connection. Tie an external capacitor across CTH pin and GND to set the setting time for the demodulation data slicing level. Values about 1nF are recommended and should be optimized for data rate and data profile. |
| DO | Demodulated data output |
