¹Measured with a low input frequency, full-scale sine wave.

²Input capacitance refers to the effective capacitance between one differential input pin and its complement.

³Input resistance refers to the effective resistance between one differential input pin and its complement.

⁴Standby 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.

⁵Power-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.
