9 / 37 page  Data Sheet AD9986 SPECIFICATIONS analog.com Rev. 0 | 9 of 37 NCO FREQUENCY SPECIFICATIONS For the minimum and maximum values, TJ = −40°C to +120°C and ±5% of nominal supply, unless otherwise noted. Table 9. Parameter Test Conditions/Comments Min Typ Max Unit MAXIMUM NUMERICALLY CONTROLLED OSCILLATOR (NCO) CLOCK RATE Fine Digital Up Converter (FDUC) NCO 1.5 GHz Course Digital Up Converter (CDUC) NCO 12 GHz Fine Digital Down Converter (FDDC) NCO 1.5 GHz Course Digital Down Converter (CDDC) NCO 6 GHz MAXIMUM NCO SHIFT FREQUENCY RANGE FDUC NCO Channel interpolation rate must be > 1× −750 +750 MHz CDUC NCO fDAC = 12 GHz, main interpolation rate must be > 1× −6 +6 GHz FDDC NCO Channel decimation rate must be > 1× −750 +750 MHz CDDC NCO fADC = 6 GHz, main decimation rate must be > 1× −3 +3 GHz MAXIMUM FREQUENCY SPACING BETWEEN CHANNELIZER CHANNELS Transmitter FDUC Channels Maximum FDUC NCO clock rate × 0.81 1200 MHz Receiver FDDC Channels Maximum FDDC NCO clock rate × 0.8142 1221 MHz 1 The 0.8 factor is because the total complex pass band of the first interpolation filter is 80% of the filter input data rate. 2 The 0.814 factor is because the total complex pass band of the decimation filter is 81.4% of the filter output data rate. JESD204B AND JESD204C INTERFACE ELECTRICAL AND SPEED SPECIFICATIONS Nominal supplies. For the minimum and maximum values, TJ = −40°C to +120°C and ±5% of nominal supply, and for the typical values, TA = 25°C, which corresponds to TJ = 80°C, unless otherwise noted. Table 10.
