ASK stands for “Amplitude Shift Keying,” which is a modulation technique used in communication systems. ASK receivers are devices designed to demodulate signals that have been modulated using amplitude shift keying.
In ASK modulation, the amplitude of the carrier signal is varied to transmit digital data. When the carrier amplitude is high, it represents one state (usually a logic “1”), and when the carrier amplitude is low or zero, it represents the other state (usually a logic “0”).
Part Number: SYN470R

Description
The SYN470R 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 the IC which eliminates manual tuning and reduces production costs. The result is a highly
reliable yet low cost solution.
Features
1. 300MHz to 440MHz frequency range
2. High receiver sensitivity: -106dBm (315MHz), -107dBm (433MHz)
3. Data-rate up to 10kbps (fixed-mode)
4. Low Power Consumption
5. 2.5mA fully operational (315MHz)
6. 0.9µA in shutdown
7. 250µA in polled operation (10:1 duty-cycle)
8. Wake-up output flag to enable decoders and microprocessors
9. Very low RF re-radiation at the antenna
10. Highly integrated with extremely low external part count
Pinouts:
Applications:
1. Automotive Remote Keyless Entry (RKE)
2. Remote controls
3. Remote fan and light control
4. Garage door and gate openers […]
