Notes:

1.Additional testing information is available in Application Note AN388. Volume = maximum for all tests. Tested at RF = 98.1 MHz.

2.To ensure proper operation and receiver performance, follow the guidelines in “AN383: Antenna Selection and Universal Layout Guidelines.” Silicon Laboratories will evaluate schematics and layouts for qualified customers.

3.FMOD = 1 kHz, 75 µs de-emphasis, MONO = enabled, and L = R unless noted otherwise.

4.Δf = 22.5 kHz.

5.BAF = 300 Hz to 15 kHz, A-weighted.

6.Guaranteed by characterization.

7.VEMF = 1 mV.

8.f2 – f1 > 2 MHz, f0 = 2 x f1 – f2. AGC is disabled. Refer to "6. Pin Descriptions: Si4734/35-GM" on page 30.

9.Δf = 75 kHz.

10.At LOUT and ROUT pins.

11.Analog audio output mode.

12.At temperature (25°C).
