ADF4153 Vs ADF4153A

alon.bendor on Jul 30, 2015

Hello

Can you advise what are the differences between ADF4153 & ADF4153A?

These parts are functional & pin to pin compatible, however the package looks a bit different.

The SW is also the same.

Are the difference performance wise?

Thanks

Alon

Hello Alan,

Improved PLL 1/f noise:

120dBc/Hz @ 10kHz offset for RF = 1GHz for ADF4153A

Compared to

114dBc/Hz @ 10kHz offset for RF = 1GHz for ADF4153

Improved PLL FOM -222.5dBc/Hz vs. -220 dBc/Hz.

Improved spurious performance -76dBc vs. -71dBc

Pin and software compatible with ADF4153

regards,

Brigid.
