GENERAL DESCRIPTION
The EVAL-ADAQ8088EBZ evaluates the ADAQ8088 and requires
a 2.7 V to 3.3 V power supply for proper operation. The EVAL-
ADAQ8088EBZ accepts baseband differential in-phase/quadrature
(I/Q) inputs via Subminiature A (SMA) connectors (Jx) and drives
pipeline analog-to-digital converters (ADCs) via SMA output con-
nectors. The EVAL-ADAQ8088EBZ contains the ADAQ8088 µMod-
ule, which is a dual-channel analog system in package (SIP) that
integrates three common signal processing and conditioning blocks
to support a variety of demodulator applications and data acquis-
ition applications. The device integrates all active and passive
components to form a complete signal chain between the output
of an I/Q demodulator and the input to an ADC. For full details
on the ADAQ8088, see the
be consulted in conjunction with this user guide when using the
EVAL-ADAQ8088EBZ.
