Silicon Laboratories' any-rate precision clocks provide clock multiplication, jitter attenuation and clock distribution in high performance timing applications requiring sub 1 ps jitter performance. The devices accept multiple clock inputs ranging from 2 kHz to 710 MHz and generate multiple independent, synchronous clock outputs ranging from 2 kHz to 945 MHz and select frequencies to 1.4 GHz.
Microprocessor controlled devices provide virtually any frequency translation combination across this operating range. For ease of use, pin-controlled devices are preconfigured to support popular SONET/SDH, Ethernet, Fibre Channel, and HDTV frequencies. The any-rate precision clocks are based on Silicon Labs' 3rd-generation DSPLL® technology, which provides any-rate frequency synthesis and 0.3 ps rms jitter performance in a highly integrated PLL solution that eliminates the need for external VCXO and loop filter components.
The DSPLL loop bandwidth is digitally programmable from 60 Hz to 8.4 kHz, providing jitter performance optimization at the application level. Devices are offered in two package options: a 6x6 mm 36-pin QFN for devices with one or two clock outputs and a 14x14 mm 100-pin TQFP for products with five clock outputs. Given their frequency flexibility and outstanding jitter performance, Silicon Labs any-rate precision clocks are ideal for providing clock multiplication, jitter attenuation and clock distribution in high-performance timing applications.
