DS26522DK Dual T1/E1/J1 Transceiver
Demo Kit

GENERAL DESCRIPTION

The DS26522DK is an easy-to-use demo kit for the
DS26522 T1/E1/J1 dual transceiver. The
DS26522DK is 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.

3. BASIC OPERATION

This design kit relies upon several supporting files, which are available for downloading on our website at
/DS26522DK QuickView page.
3.1 Hardware Configuration
• Supply 5.0V to the wall jack receptacle on the bottom of the PCB. • Install the following jumpers (see Table 5-1): JP06: MCLK driven by 1.544MHz for T1. (Set E1 for 2.048MHz.) JP01, JP03: RSYSCLK driven by MCLK. JP02, JP04: TSYSCLK driven by MCLK. JP09, JP12: TCLK driven by MCLK. JP16 SPI_SEL to GND. JP17 BTS to VCC. JP18, JP19 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.
3.1.1 General

Upon power-up, the RLF and AL_LOS LEDs (red) will be lit, but the INT LED (red) will not be lit. The board draws
approximately 200mA at power-up.
3.2 Quick Setup (Register View)

1) The PC loads ChipView, offering a choice among DEMO MODE, REGISTER VIEW, and TERMINAL
MODE. Select REGISTER VIEW.
2) The program will request a definition file. Navigate to the .def files in the T1 or E1 folder, then select the file
named DS26522_GLB_T1_DEV1.def (T1 mode) or DS26522_GLB_E1_DEV1.def (E1 mode).
Note: Through the Links section, this will also load the LIU def file and framer def file.

3) Repeat Step 2 for DS26522_GLB_T1_DEV2.def (or DS26522_GLB_E1_DEV2.def).
4) The Register View Screen will appear, showing the register names, acronyms, and values for the
DS26522.
5) 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_DEV1.ini (T1 mode) or
Load_E1_75_impMatchOn_DEV1.ini (E1 mode). Load the .ini file Load_T1_LBO0_0_133_impMatchOn_DEV2.ini (T1 mode) or
Load_E1_75_impMatchOn_DEV2.ini (E1 mode).
6) After loading the .ini file, the following may be observed: The DS26522 begins transmitting AIS with impedance match. The AL_LOS LEDs extinguishes upon external loopback.

5. TEST POINTS AND CONNECTORS

The DS26522DK has several connectors, test points, oscillators, and jumpers. Table 5-1 provides a description of
these signals, given in order of appearance on the PCB from left to right, then top to bottom (with the board held so
that the RS-232 connector is on the top edge).
