AN2719 Freescale Semiconductor / Motorola, AN2719 Datasheet - Page 3

• Manufacturer Part Number: AN2719
• Description: A Transmitter Using Tango3 (Step-by-step Design for ISM Bands)
• Manufacturer: Freescale Semiconductor / Motorola

Typical Application
A very basic transmitter can be realized with few external components.
U1 is Tango3. The internal PLL operates at a frequency that depends on the voltage level on pin BAND
and the frequency of the crystal X1.
