RFHCS362F-I/SO

KEELOQ® Code Hopping Encoder with UHF ASK/FSK Transmitter

Microchip Technology 

rfHCS362G/362F

Note 1: Standard Operating Conditions (unless otherwise stated) TA = 25°C, RFEN = 1,

VDDRF = 3V, fTRANSMIT = 433.92 MHz

2: VPS is actual voltage on PS/DATAASK pin.

3: The Power Select circuitry contains an internal 20 μA current source. To ensure that the transmitter output

power is at the minimum when transmitting a DATAASK = 0 (VSSRF), select the value of resistor R2 such

that the voltage drop across it is less than 0.1 volts.
