Jitter Cleaners Reduce Clocking BOM Cost

摘要

National Semiconductor Corporation today introduced a new family of clock jitter cleaners featuring the industry's lowest phase noise and rms jitter performance: 111 femtosecond (fs) from 12 kHz to 20 MHz, and a wideband noise floor of -162 dBc/Hz at 184 MHz output frequency. This level of phase noise enhances the performance of systems used in wireless and wired communications, test and measurement, medical imaging, software defined radio (SDR) and digital broadcast applications, while reducing overall bill of materials (BOM) cost. The LMK04800 family is comprised of four integrated circuits (ICs) including the LMK04808, LMK04806, LMK04805 and LMK04803, and is optimized for generating different frequencies up to 1.5 GHz for clocking ADCs, DACs, SerDes and FPGAs. 20 LNAs for Military and Test Instrumentation Applications Hittite Microwave Corporation has introduced two new SMT packaged GaAs pHEMT / HEMT MMIC Low Noise Amplifiers which are ideal for microwave radio, military and space and test instrumentation applications from 6 to 26.5 GHz. The HMC962LC4 and HMC963LC4 are low noise amplifiers which are rated from 7.5 to 26.5 GHz and from 6 to 26.5 GHz respectively.
