Description
The Si5369 is a jitter-attenuating precision clock multiplier for applications
requiring sub 1 ps rms jitter performance. The Si5369 accepts four clock inputs
ranging from 2 kHz to 710 MHz and generates five clock outputs ranging from
2 kHz to 945 MHz and select frequencies to 1.4 GHz. The device provides
virtually any frequency translation combination across this operating range. The
outputs are divided down separately from a common source. The Si5369 input
clock frequency and clock multiplication ratio are programmable through an I
SPI interface. The Si5369 is based on Silicon Laboratories' third-generation
DSPLL
attenuation in a highly integrated PLL solution that eliminates the need for
external VCXO and loop filter components. The DSPLL loop bandwidth is digitally
programmable, providing jitter performance optimization at the application level.
Operating from a single 1.8, 2.5 ,or 3.3 V supply, the Si5369 is ideal for providing
clock multiplication and jitter attenuation in high performance timing applications.
