DAC1627D1G25
Dual 16-bit DAC: up to 1.25 Gsps; x2, x4 and x8 interpolating
10.16.2
IQ-modulator - BGX7100 interface
The DAC1627D1G25 can be easily connected to the BGX7100 NXP IQ-modulator. The
offset compensation for local oscillator can be cancelled using the digital offset control in
the device.
Figure 24
shows an example of a connection between the DAC1627D1G25 and the
BGX7100 interface.
10.16.3
IQ-modulator - DC interface
When the system operation requires to keep the DC component of the spectrum, the
DAC1627D1G25 can use a DC interface to connect an IQ-modulator. In this case, the
offset compensation for local oscillator
can be cancelled using the digital offset control in
the device.
Figure 25
shows an example of a connection to an IQ modulator with a 1.7 V common
input level.
