DS26521DK
Single T1/E1/J1 Transceiver Design Kit
GENERAL DESCRIPTION The DS26521DK is an easy-to-use evaluation kit for
the DS26521 T1/E1/J1 single-chip transceiver (SCT).
The DS26521DK is intended to be used as a stand-
alone system. The board comes complete with a
transceiver, transformer, termination resistors,
configuration switches, network connectors,
microprocessor, and RS-232 connector. The on-
board processor and Dallas’ ChipView software give
point-and-click access to configuration and status
registers from a Windows-based PC. On-board
LEDs indicate receive loss-of-signal and interrupt
status, as well as multiple clock and signal routing
configurations.

BASIC OPERATION This design kit relies upon several supporting files, which are available for downloading on our website at
/DS26521DK QuickView page.
Hardware Configuration • Supply 3.3V to the banana-plug receptacles marked GND and VCC_3.3V. • Install the following jumpers (detailed in Table 2): • JP01—Connect MCLK to 2.048MHz (for both T1 and E1). • Connect JP02 MCLK to RSYSCLK, JP03 MCLK to TSYSCLK, JP04 TCLK to RCLK. • JP08 SPI_SEL to GND, JP09 BTS to VCC, TXENABLE to VCC. • 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 → ChipView → ChipView.
General: • Upon power-up, the RLF and AL_LOS LEDs (red) will be lit, and the INT LED (red) will not be lit. The board will
draw approximately 200mA at power-up.
Quick Setup (Register View) • The PC will load ChipView, offering a choice among DEMO MODE, REGISTER VIEW, and TERMINAL MODE.
Select REGISTER VIEW. • The program will request a definition file. Navigate to the .def files in the T1 or E1 folder, then select the file
named DS26521_GLOBAL_T1.def (T1 mode) or DS26521_GLOBAL_E1.def (E1 mode). Note: Through the
“links” section this will also load the LIU def file and framer def file. • The Register View Screen will appear, showing the register names, acronyms, and values for the DS26521. • Predefined register settings for several functions are available as initialization files. • .ini files are loaded by selecting the menu File→Reg Ini File→Load Ini File. • Load the .ini file Load_T1_LBO0_0_133_impMatchOn.ini (T1 mode) or Load_E1_75_impMatchOn.ini (E1
mode). • After loading the .ini file, the following may be observed: • The DS26521 begins transmitting AIS with impedance match. • The AL_LOS LEDs extinguishes upon external loopback.
Miscellaneous: • The DS26521 uses three register definition files. All three files are loaded when the
DS26521_GLOBAL*.def file is loaded. Individual files are selected from the Def File Selection menu in
ChipView.
