Amplitude-shift keying (ASK) and on-off keying (OOK) receivers are used for intermittent low-data-rate applications like RKE, home security, garage-door openers, and remote controls. The data that comes to an ASK or OOK receiver from a remote transmitter is reconstructed in the data slicer. The data slicer is, therefore, an integral part of ASK and FSK receivers that operate in the 260MHz to 470MHz short-range UHF band under the rules of FCC Part 15.231. This application note explains the operation of the data slicers found in Maxim's UHF receivers, including the MAX1470, MAX1473, and MAX1471, and transceivers like the MAX7030 and MAX7032.
