National Semiconductor claims its latest clock jitter cleaners features the industry’s lowest phase noise and rms jitter performance.
The company specifies jitter at 111 femtosecond (fs) from 12kHz to 20MHz, and a wideband noise floor of -162dBc/Hz at 184MHz output frequency.
The chip will find use in medical imaging, software defined radio (SDR) and digital broadcast applications, in particular.
The four devices in the
LMK04800 family are the LMK04808, LMK04806, LMK04805 and LMK04803.
They will be used to generate different frequencies up to 1.5GHz for clocking ADCs, DACs, SerDes and FPGAs.
There are holdover and switchover functions, as well as digital and analogue delay, odd/even dividers and 12 programmable output format drivers.
