6.12.1 RX Typical Characteristics 30 MHz and 400 MHz (continued)

Typical values at TA = +25°C. Default conditions at 30MHz: ADC Sampling Rate = 1500 MSPS, output sample rate = 62.5

MSPS (decimate by 24x), PLL clock mode with fREF = 500 MHz, AIN = –3 dBFS, DSA setting = 3 dB. Default conditions at

400 MHz: ADC Sampling Rate = 1500 MSPS, output sample rate = 125 MSPS (decimate by 12x), PLL clock mode with fREF

= 500 MHz, AIN = –3 dBFS, DSA setting = 3 dB.

fNCO = 400MHz
