Silicon Laboratories' programmable any frequency precision clock ICs 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 300 fs 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 4 Hz to 8.4 kHz, providing jitter performance optimization at the application level. Devices are offered in two package options: a 6 x 6 mm 36-pin QFN for devices with one or two clock outputs and a 14 x 14 mm 100-pin TQFP for products with five clock outputs. Given their frequency flexibility and outstanding jitter performance, Silicon Labs programmable any-rate precision clock ICs are ideal for providing clock multiplication, jitter attenuation and clock distribution in high-performance timing applications.
