Four-Channel Programmable Digital DownConverter
The HSP50216 Quad Programmable Digital DownConverter (QPDC) is designed for high dynamic range applications such as cellular basestations where multiple channel processing is required in a small physical space. The QPDC bines into a single package, a set of four channels which include: digital mixers, a quadrature carrier NCO, digital filters, a resampling filter, a Cartesian-to-polar coordinate converter and an AGC loop. The HSP50216 accepts four channels of 16-bit real digitized IF samples which are mixed with local quadrature sinusoids. Each channel carrier NCO...
