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
Function: 300-450MHz ASK Receiver
Package: SOP 16 Pin Type
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.
