Overview
PDSP16330/A/B Pythagoras Processor Supersedes version in December 1993 Digital Video & DSP IC Handbook, HB3923-1 DS3884 - 1.
3 September 1996 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.
Polyimide is used as an inter-layer dielectric and as glassivation.
The PDSP16330 is offered in three speed grades: a basic 10MHz part (PDSP16330), a 20MHz version (PDSP16330A) and a 25MHz version (PDSP16330).
A MILSTD-883 version is also detailed in a separate datasheet.

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...
