High-performance M/N clock generator targets small-cell wireless applications

Optimized for small-cell wireless applications, Silicon Labs' Si5380 12-output JESD204B high-performance, integer-based (M/N) clock generator is now available from Mousers stock. The devices demand the highest level of integration and phase noise performance and are based on proprietary 4th-generation DSPLL technology. The Si5380 combines frequency synthesis and jitter attenuation in a highly-integrated digital solution that eliminates the need for external VCXO and loop filter components. It includes a low cost, fixed-frequency crystal that provides frequency stability for free-run and holdover modes. The all-digital solution provides superior performance that is highly immune to external board disturbances, says the company. Typical applications include JESD204B clock generation, remote radio units (RRUs), remote access networks (RANs), picocells, small cells, wireless base stations (3G, GSM, W-CDMA, 4G/LTE, LTE-A), remote radio head (RRH), wireless repeaters, wireless backhaul, and data conversion sampling clocks (ADC, DAC, DDC, DUC).
