The ISL5217 Quad Programmable UpConverter (QPUC) is a QASK/FM modulator/FDM upconverter designed for high dynamic range applications such as cellular basestations. It combines shaping and interpolation filters, a complex modulator, and timing and carrier NCOs into a single package. Each QPUC can create four FDM channels, and 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, with multiple modulation modes and filtering options.
The ISL5217 Quad Programmable Up Converter (QPUC) converts digital baseband data into various modulated formats, supporting QASK, FM, and vector modulation for applications such as cellular base stations. It offers four independent channels, each with a 256‑tap FIR filter and programmable NCOs for carrier and symbol timing.
The device is configured via a 16‑bit microprocessor interface with parallel and serial data paths, includes a FIFO that can store up to seven I/Q sample pairs, and operates with supply voltages of 2.5 V (core) and 3.3 V (I/O). It supports output sample rates up to 104 MSPS and input rates up to 6.5 MSPS, with an operating temperature range of –40 °C to 85 °C.
