Description
The Si535/536 XO utilizes Silicon Labs’ advanced DSPLL
®
circuitry to
provide an ultra low jitter clock at high-speed differential frequencies. Unlike a
traditional XO, where a different crystal is required for each output frequency,
the Si535/536 uses one fixed crystal to provide a wide range of output
frequencies. This IC based approach allows the crystal resonator to provide
exceptional frequency stability and reliability. In addition, DSPLL clock
synthesis provides superior supply noise rejection, simplifying the task of
generating low jitter clocks in noisy environments typically found in
communication systems. The Si535/536 IC based XO is factory programmed
at time of shipment, thereby eliminating long lead times associated with
custom oscillators.

In serial communication mode 3, the ninth bit RB8 is always zero
As the title says. Whether debugging in software (odd parity) or in hardware, RB8 is always zero. For example, if I send 9, RB8==0, and if I send 7 it is also 0. Please help me. Thank you void STR_int...
