TDF8599

Class-D power ampliﬁer with load diagnostics

The spread spectrum frequency can be calculated using:

(2)

where the voltage on pin OSCSET = V1 and is calculated as 100 µA × Rosc (V) with

ISSM =5 µA.

The frequency swings between 0.95

× f

osc and 1.05 × fosc, see Figure 8.

8.3.3 Frequency hopping (Master mode)

Frequency hopping is a technique used to change the oscillator frequency for AM tuner

compatibility. In Master mode, the resistor connected between pin OSCSET and pin

AGND sets the oscillator frequency. In I2C-bus mode, this frequency can be varied by

10 % to 0.9

× f

osc or 1.1 × fosc using bit IB1[D3:D4]. See Figure 8.

8.3.4 Phase lock operation (Slave mode)

In Slave mode, phase lock operation can be used to reduce the jitter effects of the external

oscillator signal connected to pin OSCIO. Phase lock operation is also needed to enable

phase staggering, see Section 8.4.2. Phase lock operation is enabled when the oscillator

is in Slave mode by connecting two capacitors (CPLL_S and CPLL_p) and a resistor (RPLL)

between pin SSM and pin AGND (see Figure 9). Connecting pin SSM to pin AGND

disables phase lock operation and causes the slave to use the external oscillator signal
