Component Footprints and Symbols in the Binary .Bxl File Format
by Richard Anslow
Rev. 0 | Page 1 of 8
INTRODUCTION
Analog Devices, Inc., provides symbols and footprints for
components created in a single format, that is, a binary Xlator
(.bxl) file. The .bxl files have been created using the Ultra
Librarian tool offered by Accelerated Designs, Inc. A free
version of the Ultra Librarian Reader is available online from
the Accelerated Designs website.
Customers can download the Ultra Librarian Reader to open
the component binary .bxl file. For example, Analog Devices
has created a .bxl file for the ADM2587E isolated RS-485/
RS-422 transceiver. This .bxl file webpage provides a link to
download the Ultra Librarian Reader.
Once the .bxl file is opened, the Ultra Librarian Reader allows
the footprint and symbol to be exported to one of many CAD
toolsets, including Cadence® Allegro®, Allegro®OrCAD®,
Accel15/PCAD 2xxx/Altium6, Mentor PADS®, PowerPCB, and
Zuken, Inc., CADSTAR®.
These toolsets cover 97% of CAD users, and thus enable Analog
Devices to offer component footprints and symbols to meet the
vast majority of customer needs.
IMPORTING A BINARY FILE TO THE ULTRA
LIBRARIAN READER AND EXPORTING TO A CAD
TOOL
The examples in this application note illustrate how the
Ultra Librarian Reader is used with
• the ADM2587E isolated RS-485/RS-422 transceiver
ADM2587EBRWZ.bxl file
• the ADM3053 signal and power isolated CAN transceiver
ADM3053BRWZ.bxl file
• the ADN4697E multipoint, low voltage differential
signaling (M-LVDS) transceiver ADN4697EBRZ.bxl file.
The ADM2587E is a fully integrated signal and power isolated
RS-485/RS-422 data transceiver with ±15 kV ESD protection,
which is suitable for high speed communication on multipoint
transmission lines. The ADM2587E includes an integrated
isolated dc-to-dc power supply (Analog Devices isoPower®),
which eliminates the need for an external dc-to-dc isolation
block. The device integrates the Analog Devices iCoupler®
technology to combine a three-channel isolator, a three-state
differential line driver, a differential input receiver, and
isoPower.
The ADN4697E is a multipoint low voltage differential
signaling (M-LVDS) transceiver (driver and receiver pair) that
can operate at up to 200 Mbps (100 MHz). The receiver detects
the bus state with a differential input of as little as 50 mV over a
common-mode voltage range of −1 V to +3.4 V. ESD protection
of up to ±15 kV is implemented on the bus pins.
The ADM3053 is an isolated controller area network (CAN)
physical layer transceiver with an integrated isolated dc-to-
dc converter. The device integrates iCoupler and isoPower
technology. The ADM3053 creates a fully isolated interface
between the CAN protocol controller and the physical layer
bus. It is capable of running at data rates of up to 1 Mbps.
