LMX2571: LMX2571 & LMX2572 comparison

Expert 4100 points

Part Number: LMX2571
Other Parts Discussed in Thread: CDCE913, LMK03318, , LMX2572

Hi Team,

Customer want to generate 48MHz and 64MHz clock with very low power consumption and good phase noise. They have seen LMK03318 and CDCE913 and now move to LMX257x.

For LMX2572 and LMX2571, how about your comments on the phase stability and phase noise performance @40MHz ~ 150MHz output frequency? Any test report related with that?

Thank you!

Marc

    Hi Marc,

    These LMX devices cannot generate both 48MHz and 64MHz simultaneously. They can generate 48MHz, 64MHz or any other clock frequencies, one frequency at a time. 

    These devices are mainly used in the comms market and other proprietary wireless systems, there is no questions to their performance. 

    The performance of LMX2572 is better than LMX2571, however, LMX2572 burns more power than LMX2571.
