I wonder how to test CMRR and Slew rate of ADL5202.
and plz recommend the test configuration.
I can only comment on how these measurements are generally performed:
CMRR is measured by putting the same signal (i.e., common-mode signal, e.g., 1Vpp 100 MHz sinewave) to both sides of the differential inputs, and noting the differential output signal level; then a differential of the same frequency is applied to the inputs to produce the same output level. The ratio of the common-mode input signal level to the differential input level is CMRR, expressed in dB.
Slew Rate is measured by applying a square wave with fast edge rates (deltaV/deltaT, must be much faster than the 5V/ns specified for the ADL5202) to achieve a specified output level (e.g., 2Vpp). Then the edge rates of the output signal (both rising and falling edges) are measured and expressed in V/ns.
Thank you for the reply.
