Jitter Atten Freq Translators

IDT VCXO PLL devices are synchronous jitter attenuation and frequency translation products featuring a VCXO-based PLL stage with either internal VCXO requiring only an external pullable crystal, or with an external low-frequency VCXO. This PLL stage is typically configured with low loop bandwidth to provide jitter attenuation. It can also accommodate numerous predividers and feedback dividers to allow for frequency translation. The output frequency from the VCXO PLL stage is then followed by a frequency multiplier that provides the capability to generate output frequencies up to 800 MHz with typical random phase-noise jitter of 1ps RMS. These devices can be used in many applications to replace expensive VCSO PLLs. Applications for IDT VCXO PLL devices include synchronous Ethernet, wireless infrastructure, SONET/SDH, telecom and professional video.
