HSP50215 Digital UpConverter

NAME VCC GND C(15:0) TYPE I/O +5V Power supply input. Power supply ground input. µP Bidirectional Data bus. The C(15:0) bus is used for loading the conﬁguration data and sample vectors for modulation. C15 is the MSB. µP Address Bus. The A(9:0) bus is used for addressing the proper registers for loa.

HSP50215 Data Sheet January 1999 File Number 4346.4 Digital UpConverter The HSP50215 Digital UpConverter (DUC) is a QASK/FM modulator/FDM upconverter designed for high dynamic range applications such as cellular basestations. The DUC combines shaping and interpolation filters, a complex modulator, and Timing and Carrier NCO’s into a single package. Each DUC can create a single FDM channel. Multiple DUC’s can be cascaded digitally for multi-channel applications. The HSP50215 supports both vector.
