Part Number: LMX2594
Other Parts Discussed in Thread: LMX2491, LMX2541, LMX2531

Does the LMX2594 have a pushing spec similar to the spec provided for the LMX2491 (600kHz/V)?

    Hi Steve,

    LMX2491 is a PLL only device, I though you were trying to say LMX2541 :)

    Starting from LMX2531, we implemented internal LDO to eliminate frequency pushing effect to the VCO. Both LMX2531 and LMX2541 have similar pushing performance. so for the later devices we didn't put this spec in the datasheet anymore as we believe the pushing performance will be same. In fact, this spec is not important anymore as the pushing effect has been isolated by the internal LDO.
