Quad Programmable Up Converter
The ISL5217 Quad Programmable UpConverter (QPUC) is a
QASK/FM modulator/FDM upconverter designed for high
dynamic range applications such as cellular basestations. The
QPUC combines shaping and interpolation filters, a complex
modulator, and timing and carrier NCOs into a single package.
Each QPUC can create four FDM channels. Multiple QPUCs can
be cascaded digitally to provide for up to 16 FDM channels in
multi-channel applications.
The ISL5217 supports both vector and FM modulation. In vector
modulation mode, the QPUC accepts 16-bit I and Q samples to
generate virtually any quadrature AM or PM modulation format.
The QPUC also has two FM modulation modes. In the FM with
pulse shaping mode, the 16-bit frequency samples are pulse
shaped/bandlimited prior to FM modulation. No band limiting filter
follows the FM modulator. This FM mode is useful for GMSK type
modulation formats. In the FM with band limiting filter mode, the
16-bit frequency samples directly drive the FM modulator. The
FM modulator output is filtered to limit the spectral occupancy.
This FM mode is useful for analog FM or FSK modulation
formats.
The QPUC includes an NCO driven interpolation filter, which
allows the input and output sample rate to have an integer
and/or variable relationship. This re-sampling feature
simplifies cascading modulators with sample rates that do not
have harmonic or integer frequency relationships.
The QPUC offers digital output spectral purity that exceeds
100dB at the maximum output sample rate of 104MSPS, for
input sample rates as high as 6.5MSPS.
A 16-bit microprocessor compatible interface is used to load
configuration and baseband data. A programmable FIFO depth
interrupt simplifies the interface to the I and Q input FIFOs.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate termination finish,
which are RoHS compliant and compatible with both SnPb and Pb-free soldering
operations. Intersil Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
