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.

Universal Antenna Selection and Layout Guidelines.” Silicon Laboratories will evaluate schematics and layouts for
qualified customers. Tested with test schematic (L = 120 nH, Q > 30) shown in Figure 9 on page 14.
Supported Parameter
Therefore, the range of RCLK frequencies is not continuous below frequencies of 311.3 kHz.
