[c]

The input 0.1dB compression point is a linearity figure of merit. Refer to “Absolute Maximum Ratings” section for the maximum RF input

power. This specification is measured in a 50Ω system.

[d]

Spurious due to on-chip negative voltage generator. Typical generator fundamental frequency is 2.2MHz.

[e]

Speeds are measured after SPI programming is completed (data latched with LE = HIGH).
