1. The 640 MHz frequency is achieved with a 10 MHz or 20 MHz reference clock. With a 26 MHz reference, the VCO
frequency is 624 MHz.
2. The time from the PLL enable bit register write to the start of phase locks is maximum 2 clock cycles of the peripheral
bridge clock that is connected to the PLL on the device.
3. Measured at the transmitter output across a 100 Ohm termination resistor on a device evaluation board. Refer to the figure
below.
