Quad Programmable Up Converter
FN6004 Rev. 3.00 July 8, 2005
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 bines shaping and interpolation filters, a plex 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...
