Design Notes
Host
The Q58 requires only a power supply and SPI bus connection to operate. Conditioning
circuitry prevents host power supply noise from adversely affecting radio performance.
Nevertheless, good design and layout practices will insure optimum performance. Keep
power and signal traces connected to the Q58 separated from noisy clocks and
fast-transition signals. Switching power supplies with switching frequencies above
500kHz are optimal. Power supply ripple should be 100mV or less. Connections to
power pins should be wider than signal pins and appropriate for the maximum current.
