Description
The Si570 XO/Si571 VCXO utilizes Silicon Laboratories’ advanced DSPLL
®
circuitry to provide a low-jitter clock at any frequency. The Si570/Si571 are user-
programmable to any output frequency from 10 to 945 MHz and select frequencies
to 1400 MHz with <1 ppb resolution. The device is programmed via an I
2
C serial
interface. Unlike traditional XO/VCXOs where a different crystal is required for
each output frequency, the Si57x uses one fixed-frequency crystal and a DSPLL
clock synthesis IC to provide any-frequency operation. 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.

Someone from Huazhong University of Science and Technology told me about Arm development. Is that correct?
He told me that if I want to get an Arm development board, I need to use Keil to write the underlying driver first, and then transfer the code written in Keil to Platform Builder to run. Can't Platfor...

In the TMS570 program, what are 0xffffffffU; and 16384U respectively?
In the above program, U is used in many places, such as: 0xffffffffU; 0x00000005U; 16384U - 1U Obviously: 0xffffffffU and 16384U - 1U does not represent the same base. Can 0xffffffffU be understood as...
