Antenna driver output resistance
Measured with subcarrier signal at RX_IN1 or RX_IN2 and measured the digital output at MOD pin with register 0x1A bit 6 = 1.
Depends on the crystal parameters and components
Recommended DATA_CLK speed is 2 MHz. Higher data clock depends on the capacitive load. Maximum SPI clock speed should not
exceed 10 MHz. This clock speed is acceptable only when external capacitive load is less than 30 pF. MISO driver has a typical output
resistance of 400 Ω (12-ns time constant when 30-pF load used).
