AIS Baseband IC with/without RF Synthesiser
CMX7032/CMX7042
8.1.3 Operating Characteristics
For the following conditions unless otherwise specified:
External components as recommended in Figure 2.
Maximum load on digital outputs = 30pF.
Clock Frequency = 19.2MHz (20ppm); Tamb = 40°C to +85°C.
AV = DV = CPV = 3.0V to 3.6V; RFV = 2.25V to 2.75V.

Reference signal level = 300mV pk-pk with AV = 3.3V.
DD
Signal levels track with supply voltage, so scale accordingly.
Signal to Noise Ratio (SNR) in bit rate bandwidth.
Input stage gain = 0dB. Output stage attenuation = 0dB.
