PDSP16330B, PDSP16330, Pythagoras Processor

The PDSP16330 converts incoming Cartesian Data into the equivalent Polar Values.

The device accepts new 16 + 16 bit complex data every cycle, and delivers a 16 bit + 12 bit Polar equivalent after 24 clock cycles.The input data can be in 2s’ Complement or Sign Magnitude format selected via the FORM i

www.DataSheet4U.com PDSP16330/A/B Pythagoras Processor DS3884 ISSUE 2.1 November 1998 The PDSP16330 is a high speed digital CMOS IC that converts Cartesian data (Real and Imaginary) into Polar form (Magnitude and Phase), at rates up to 20MHz.

Cartesian 16+16 bit 2's complement or Sign-Magnitude data is converted into 16 bit Phase format.

The Magnitude output may be scaled in amplitude by powers of 2.

The Phase output represents a full 2 x π field to eliminate phase ambiguities.
