GENERAL DESCRIPTION
The DS21352 design kit is an evaluation board for
the DS21352. The DS21352DK is intended to be
used as a daughter card with either the DK2000 or
the DK101 motherboards. The board is complete with
a single-chip transceiver (SCT), transformers,
termination resistors, configuration switches, line
protection circuitry, network connectors, and an
interface to the motherboard.

BASIC OPERATION
This design kit relies upon several supporting files, which can be downloaded from our website at
www.maxim-
ic.com/DS21352DK
.
Hardware Configuration
Using the DK101 processor board:
Connect the daughter card to the DK101 processor board.
Supply 3.3V to the banana-plug receptacles marked GND and VCC_3.3V. (The external 5V connector and the
TIM 5V supply headers are unused.)
All processor board DIP switch settings should be in the ON position with exception for the flash programming
switch, which should be OFF.
From the Programs menu launch the host application named ChipView.exe. Run the ChipView application. If
the default installation options were used, click the Start button on the Windows toolbar and select
Programs
ChipViewChipView.
Using the DK2000 processor board:
Connect the daughter card to the DK2000 processor board.
Connect J1 to the power supply that is delivered with the kit. Alternately, a PC power supply can be connected
to connector J2.
From the Programs menu launch the host application named ChipView.exe. Run the ChipView application. If
the default installation options were used, click the Start button on the Windows toolbar and select
Programs
ChipViewChipView.
General:
Upon power-up the RLOS LED is lit, as well as the MCLK-2.048MHz and TCLK-2.048MHz LEDs.
Quick Setup (Demo Mode)
The PC loads the program, offering a choice among Demo Mode, Register View, and Terminal Mode. Select
Demo Mode.
The program requests a configuration file, then select DS21352DK_DRVR.cfg.
The Demo Mode screen appears. Upon external loopback, the LOS and OOF indicators extinguish.
Quick Setup (Register View)
The PC loads the program, offering a choice among Demo Mode, Register View, and Terminal Mode. Select
Register View.
The program requests a definition file, then select DS21352.def.
The Register View screen appears, showing the register names, acronyms, and values. Note: During th
edefinition file load process, all registers are initialized according to the init value filed in the definition file
(because the SETUP field in the .def file is turned on).
Predefined register settings for several functions are available as initialization files.
INI files are loaded by selecting the menu FileReg Ini FileLoad Ini File.
Load the INI file DS21352t1_b8zs_esf.ini.
After loading the INI file the following may be observed:
The RLOS LED extinguishes upon external loopback.
The device is now configured for T1 B8ZS ESF.
Miscellaneous:
Clock frequencies and certain pin bias levels are provided by a register-mapped CPLD, which is on the
DS21352 daughter card.
The definition file for this CPLD is named DS215x_35x_CPLD_V2.def. See the
CPLD Register Map
section for
definitions.
All files referenced above are available for download in the section marked "File Locations."

Please see the data sheet(s) for details.
Registers in the CPLD can be easily modified using ChipView.exe, a host-based user interface software, along with
the definition file named DS215x_35x_CPLD_V2.def. Definition files for the SCT are named DS2155.def,
DS21352.def, or DS21354.def, depending on the board population option.
