1. FM transmitter performance specifications are subject to adherence to Silicon Laboratories guidelines in “AN383:
2. Guaranteed by characterization.
3. No measurable fRF/V
1. Guaranteed by characterization.
2. The RCLK frequency divided by an integer number (the prescaler value) must fall in the range of 31,130 to 34,406 Hz.
