PDSP16330/A/B
Pythagoras Processor
Supersedes version September 1996, DS3884 - 1.3
DS3884 - 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.
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 MIL-
STD-883 version is also detailed in a separate datasheet.
