INTRODUCTION
The ZR7386014 Richmond is the new member of Zoran’s
ZBridge family of reference designs featuring the ZR38601 and
ZR38650 Digital Audio Processors. These two processors add
important new features to the Zoran’s industry standard
ZR38600: a processing speed of 50 MIPS (up from 40 MIPS),
and the Z2C two-wire serial port.
The ZBridge family currently consists of:
Golden Gate
San Mateo
ZR73865001
ZR7386012[1]
Richmond
ZR7386014
Motherboard
ZR73865002MB
All known decoding of digital audio signals can be met with this
family. All processors run the extensive library of certified Sili-
conSoftwareTM applications, and are fully supported by Zoran’s
Audio Products Team. SiliconSoftware are applications for the
ZR38600 family of programmable digital audio processors by
Zoran and qualified third-parties, and guaranteed to run
perfectly.
Each of the ZBridge reference designs is available as a ready to
use, miniature pc board that may be plugged into the users main
board, or the Mother Board (ZR73865002MB). All three Z-
Bridge designs share this common mother board, which con-
taining useful interface signal buffers and other conveniences
that will speed host product development and integration.
ZBridge reference designs and the mother board give the user
examples of working processor and interface circuitry that meet
stringent consumer audio industry standards and the various
licensing authorities.
To speed users Time To Market, Zoran supplies schematics,
layouts, parts lists, and design data to qualified OEM customers
at no charge. This data sheet describes the Richmond model, as
shown in the block diagram above. See page 2 for the block
diagrams of the other ZBridge family members.
