Notes:
1. Guaranteed by design. Typical values are at V_DD = 3.3V , T_a = 25°C ambient and maximum loading.
2. S parameters are measured with our evaluation board made with Rogers (R04350) material. Trace width is 30 mil, length 540 mil, trace
impedance is 50 Ohm (+/-5%) and total insertion loss of the trace is 0.5dB@4GHz.
3. Measurement done with fixture deembedding.
