Measured with a low input frequency, full-scale sine wave.

2

Input capacitance refers to the effective capacitance between one differential input pin and its complement.

3

Input resistance refers to the effective resistance between one differential input pin and its complement.

4

Standby power is measured with a low input frequency, full-scale sine wave, and the CLK± pins active. Address 0x08 is set to 0x20, and the PDWN pin is asserted.

5

Power-down power is measured with a low input frequency, a full-scale sine wave, RFCLK pulled high, and the CLK± pins active. Address 0x08 is set to 0x00, and the

PDWN pin is asserted.
