8.4.2 Phase staggering (Slave mode)

In Slave mode with phase lock operation enabled, a phase shift with respect to the

incoming clock signal can be selected to distribute the switching moments over time. In

non-I2C-bus mode, 1⁄2 π phase shift can be programmed using pin MOD. In I2C-bus mode,

five different phase shifts (1⁄4 π, 1⁄3 π, 1⁄2 π, 2⁄3 π, 3⁄4 π) can be selected using the I2C-bus

bits (IB3[D1:D3]). See Figure 9 for selection of the phase shift in non-I2C-bus mode with

pin MOD. An additional capacitor must be connected to pin SSM when 1⁄4 π phase shift is

used (see Figure 9). An example of using 1⁄2 π phase shift for BD modulation is shown in

Figure 13.
