APx PDM I/O Module for B Series: Specifications

PDM

PDM input/output module specifications

with APx500 v5.0 or higher measurement software

as fitted in APx517, 52x, 555 and 58x B Series audio analyzers

NP0020.00036 rev 002

March, 2020

This illustration shows the PDM module, model 236.

The PDM option provides a complete solution for addressing circuits or devices with a PDM

input or output. The PDM signal output consists of an APx generator audio signal, interpo-

lated by a broad choice of oversampling ratios, and modulated into a 1-bit PDM bitstream. A

4th-order modulator is the default; a 5th-order modulator can be selected. The PDM Option

also provides a signal input with its associated clock connection. The input accepts a 1-bit

PDM bitstream, which is then decimated by one of a wide range of decimation ratios and fil-

tered into baseband audio at the Decimated Rate. The input bitstream can also be analyzed

directly (before decimation) in the Signal Analyzer to view out-of-band components.

These specifications cover the digital input and output functions of the Audio Precision PDM

interface for the current version, model 236.

PDM specifications begin on the next page.
