3. BASIC OPERATION
This design kit relies upon several supporting files, which are available for downloading on our website at
www.maxim-ic.com/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):
o JP06: MCLK driven by 1.544MHz for T1. (Set E1 for 2.048MHz.)
o JP01, JP03: RSYSCLK driven by MCLK.
o JP02, JP04: TSYSCLK driven by MCLK.
o JP09, JP12: TCLK driven by MCLK.
o 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 Chi pView
application. If the default installation options were used, click the Start button on the Windows toolbar a nd
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 DE MO 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 sele ct 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.
o .ini files are loaded by selecting the menu File→Reg Ini File→Load Ini File.
o Load the .ini file Load_T1_LBO0_0_133_impMatchOn_DEV1.ini (T1 mode) or
Load_E1_75_impMatchOn_DEV1.ini (E1 mode).
o Load the .ini file Load_T1_LBO0_0_133_impMatchOn_DEV2.ini (T1 mode) or
Load_E1_75_impMatchO n_DEV2.ini (E1 mode).
6) After loading the .ini file, the following may be observed:
o The DS26522 begins transmitting AIS with impedan ce match.
o The AL_LOS LEDs extinguishes upon external loopback.
3.2.1 Miscellaneous
The DS26522 uses three registe r definition files. All three files are loaded when the DS26522_GLOBAL*.def file is
loaded. Individual files are selected from the Def File Selection menu in ChipView.
