Stand Alone FFT Processor

Advance Information

DS3762

ISSUE 3.0

October 1998

The PDSP16510 performs Forward or Inverse Fast

FourierTransformsoncomplexorrealdatasetscontainingup

to 1024 points. Data and coefficients are each represented by

16 bits, with block floating point arithmetic for increased

dynamic range.

DATA INPUT

3 TERM

WINDOW

OPERATOR

An internal RAM is provided which can hold up to 1024

complex data points. This removes the memory transfer

bottleneck, inherent in building block solutions. Its organisa-

tion allows the PDSP16510 to simultaneously input new data,

transform data stored in the RAM, and to output previous

results. No external buffering is needed for transforms con-

taining up to 256 points, and the PDSP16510 can be directly

connected to an A/D converter to perform continuous trans-

forms. The user can choose to overlap data blocks by either

0%, 50%, or 75%. Inputs and outputs are asynchronous to the

40MHz system clock used for internal operations.

BUFFER

A 1024 point complex transform can be completed in

some 98µs, which is equivalent to throughput rates of 450

million operations per second. Multiple devices can be con-

nected in parallel in order to increase the sampling rate up to

the 40MHz system clock. Six devices are needed to give the

maximum performance with 1024 point transforms.

can be internally applied to the incoming real or complex data.

The latter gives 67dB side lobe attenuation. The operator

values are calculated internally and do not require an external

ROM nor do they incur any time penalty.

Internal window operator gives 67dB side lobe

attenuation and needs no external ROM.

NOTE

Polyimide is used as an inter-layer dielectric and as

glassivation.

132 pin surface mount package

Polymeric material is also used for die attach which according

to the requirement in paragraph 1.2.1.b. (2) precludes

catagorising this device as fully compliant. In every other

respect this device has been manufactured and screened in

full accordance with the requirements of Mil-Std 883 (latest

revision).

CHANGE NOTIFICATION

PDSP16510A MA AC1R

(Power Ceramic PGA Package

- HIREL LEVEL A Screening)

The change notification requirements of MIL-PRF-38535 will

be implemented on this device type. Known customers will be

notified of any changes since the last buy when ordering

further parts if significant changes have been made.
