PDSP16330 MC
Pythagoras Processor
Supersedes October 1995 version, DS3240 - 2.1
DS3240 - 3.1 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 10MHz. 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.
