Freescale SMeCm33ic49o2nductor, Inc.

ELECTRICAL CHARACTERISTICS

Unless otherwise specified: Vcc=3V, Rext=12kΩ, operating temperature range TA=-40°C to +125°C, RF output

frequency fcarrier=433.92MHz, reference frequency freference=13.56MHz, output load = 50Ω resistor (see figure 7).

Values refer to the circuit shown in the recommended application schematic (see figure 10).

Typical values reflect average measurement at VCC=3V and TA=25°C.
