ISL5416
Four-Channel Wideband Programmable
DownConverter
The ISL5416 Four-Channel Wideband Programmable Digital
DownConverter (WPDC) is designed for high dynamic range
applications such as cellular basestations where the
processing of multiple channels is required in a small
physical space. The WPDC combines four channels in a
single package, each including: an NCO, a digital mixer,
digital filters, an AGC and a resampling filter.
All channels are independently programmable and may be
updated in real time. Each of the four channels can select
any of the four digital input buses. Each of the tuners can
process a W-CDMA channel. Channels may be cascaded or
polyphased for increased bandwidth. Selectable outputs
include I samples, Q samples, and AGC gain. Outputs from
the part are available over the parallel, serial or uP
interfaces.

NOTE: Intersil Pb-free products employ special Pb-free material sets; molding
compounds/die attach materials and 100% matte tin plate termination finish, which is
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-020B.
