National Semiconductor clock jitter cleaner range

Monday, 25 April, 2011 | Supplied by: Arrow Electronics Australia Pty Ltd


National Semiconductor has introduced a family of clock jitter cleaners featuring what it claims is 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.

This level of phase noise enhances the performance of systems used in wireless and wired communications, test and measurement, medical imaging, software-defined radio and digital broadcast applications, while reducing overall bill of materials cost.

The LMK04800 family comprises four integrated circuits including the LMK04808, LMK04806, LMK04805 and LMK04803 and is optimised for generating different frequencies up to 1.5 GHz for clocking ADCs, DACs, SerDes and FPGAs.

With integrated features such as holdover, switchover, multiple inputs, digital delay, analog delay, odd/even dividers and 12 programmable output format drivers, the LMK04800 ICs are flexible and configurable to support a variety of different architectures.
