Si5325
P-P ROGRAMMABLE P RECISION C LOCK M ULTIPLIER
Features
Applications
Description
The Si5325 is a low jitter, precision clock multiplier for applications requiring clock
multiplication without jitter attenuation. The Si5325 accepts dual clock inputs
ranging from 10 to 710 MHz and generates two clock outputs ranging from 2 kHz
to 945 MHz and select frequencies to 1.4 GHz. The two outputs are divided down
separately from a common source. The device provides frequency translation
combinations across this operating range. The Si5325 input clock frequency and
clock multiplication ratio are programmable through an I2C or SPI interface. The
Si5325 is based on Silicon Laboratories' 3rd-generation DSPLL technology,
which provides frequency synthesis in a highly integrated PLL solution that
eliminates the need for external VCXO and loop filter components. The DSPLL
loop bandwidth is digitally programmable. Operating from a single 1.8, 2.5, or
3.3 V supply, the Si5325 is ideal for providing clock multiplication in high
performance timing applications
.
Not recommended for new
designs. For alternatives, see the
Si533x family of products.
