that can range from 150 kHz to 1.3 MHz. No external components are required for these devices. LOS and FOS
monitoring is available for these devices, as described above.
The Any-Rate Precision Clocks have differential clock output(s) with programmable signal formats to support
LVPECL, LVDS, CML, and CMOS loads. If the CMOS signal format is selected, each differential output buffer
generates two in-phase CMOS clocks at the same frequency. For system-level debugging, a PLL Bypass Mode
drives the clock output directly from the selected input clock, bypassing the internal PLL.
Silicon Laboratories offers a PC-based software utility, DSPLLsim that can be used to determine valid frequency
plans and loop bandwidth settings for the Any-Rate Precision Clock product family. For the microprocessor-
controlled devices, DSPLLsim provides the optimum PLL divider settings for a given input frequency/clock
multiplication ratio combination that minimizes phase noise and power consumption. DSPLLsim can also be used
to simplify device selection and configuration. This utility can be downloaded from http://www.silabs.com/timing.
Other useful documentation, including device data sheets and programming files for the microprocessor-controlled
devices are available from this website.
