8. Functional description

The TDA9901 provides a digitally controlled variable gain function for high-frequency

applications.

The TDA9901 can be operated in two different modes, depending on the value at pin TE.

When TE is at logic 1, the gain can be instantly controlled when the clock signal is HIGH

(transparent mode). The gain is ﬁxed during the LOW period of the clock. When TE is at

logic 0 the gain of the TDA9901 is changed at the rising edge of the clock signal.
