VGA and CW Mixer Operation
During normal operation, the device is configured so
that either the VGA path is enabled while the mixer array
is powered down (VGA mode), or the quadrature mixer
array is enabled while the VGA path is powered down
(CW mode). For VGA mode, set CWD to a logic-high, and
for CW mode, set CWD to a logic-low.
External Voltage Reference
Connect an external, low-noise, +2.5V reference to the
VREF pin. Bypass VREF to ground with a 0.1FF capaci-
tor as close as possible to the device. The device noise
performance is dependent on the external noise at VREF.
ADC Clock Input
The input clock interface provides for flexibility in the
requirements of the clock driver. The device accepts
a fully differential clock or single-ended logic-level
clock. The device is specified for an input sampling
25MHz to 50MHz frequency range. By default, the
internal phase-locked loop (PLL) is configured to
accept input clock frequencies from 39MHz to 50MHz.
The PLL is programmed through the PLL Sampling Rate
register (00h, Table 4). Table 5 details the complete
range of PLL sampling frequency settings.
For differential clock operation, connect a differential
clock to the CLKIN+ and CLKIN- inputs. The input
