Product data sheet Rev. 01 — 29 July 2009 8 of 54 NXP Semiconductors TDF8599B I2C-bus controlled dual channel class-D power amplifier The value of the resistor Rosc sets the clock frequency based on Equation 1: (1) In Master mode, Spread spectrum mode and frequency hopping can be enabled. In Slave mode, phase staggering and phase lock operation can be selected. An external clock can be used as the master-clock on pin OSCIO of the slave devices. When using an external clock, it must remain active during the shutdown sequence to ensure that all devices are switched off and able to enter the off state as described in Section 8.2 on page 6. In Slave mode, an internal watchdog timer on pin OSCIO is triggered when the TDF8599B is switched off by pulling down pin EN. If the external clock fails, the watchdog timer forces the TDF8599B to switch off. 8.3.2 Spread spectrum mode (Master mode) Spread spectrum mode is a technique of modulating the oscillator frequency with a slowly varying signal to broaden the switching spectrum, thereby reducing the spectral density of the EMI. Connecting a capacitor (CSSM) to pin SSM enables Spread spectrum mode (see Figure 6). When pin SSM is connected to pin AGND, Spread spectrum mode is disabled. Fig 4.
