Multistandard hybrid IF processing
[28] The tolerance of the reference frequency determines the accuracy of VIF AFC, RIF AFC, FM demodulator center frequency, maximum
FM deviation, sound trap frequency, LIF band-pass cut-off frequency, as well as the accuracy of the synthesizer.
[29] The value of Cpull determines the accuracy of the resonance frequency of the crystal. It depends on the used type of crystal.
[30] The AC characteristics are in accordance with the I2C-bus specication for fast mode (maximum clock frequency is 400 kHz).
Information about the I2C-bus can be found in the brochure
“The I2C-bus and how to use it” (order number 9398 393 40011).
[31] The SDA and SCL lines will not be pulled down if VP is switched off.
[32] The threshold is dependent on VP.
[33] The threshold is independent of VP.
