Power Dissipation
T he power dissipation of the AD9059 is specified to reflect a
typical application setup under the following conditions: en-
code is 60 MSPS, analog input is –0.5 dBFS at 10.3 MHz, V
D
is +5 V, V
DD
is +3 V, and digital outputs are loaded with 7 pF
typical (10 pF maximum). T he actual dissipation will vary as
these conditions are modified in user applications. Figure 8
shows typical power consumption for the AD9059 versus ADC
encode frequency and V
DD
supply voltage.

A power-down function allows users to reduce power dissipa-
tion when ADC data is not required. A T T L/CMOS HIGH
signal (PWRDN) shuts down portions of the dual ADC and
brings total power dissipation to less than 10 mW. T he internal
bandgap voltage reference remains active during power-down
mode to minimize ADC reactivation time. If the power-down
function is not desired, Pin 3 should be tied to ground. Both
ADC channels are controlled simultaneously by the PWRDN
pin; they cannot be shut down or turned on independently.
Applications
T he wide analog bandwidth of the AD9059 makes it attractive
for a variety of high performance receiver and encoder applica-
tions. Figure 16 shows the dual ADC in a typical low cost I & Q
demodulator implementation for cable, satellite, or wireless
LAN modem receivers. T he excellent dynamic performance of
the ADC at higher analog input frequencies and encode rates
empowers users to employ direct IF sampling techniques (refer
to Figure 3,
Spectral Plot
). IF sampling eliminates or simplifies
analog mixer and filter stages to reduce total system cost and
power.

T he high sampling rate and analog bandwidth of the AD9059
are ideal for computer RGB video digitizer applications. With a
full-power analog bandwidth of 2
×
the maximum sampling rate,
the ADC provides sufficient pixel-to-pixel transient settling
time to ensure accurate 60 MSPS video digitization. Figure 17
shows a typical RGB video digitizer implementation for the
AD9059.
