DS26401DK
Octal T1/E1/J1 Framer Design Kit Daughter Card
GENERAL DESCRIPTION The DS26401DK is an easy-to-use evaluation board for the DS26401 octal T1/E1/J1 framer. It is intended to be used as a daughter card with the DK101
motherboard or the DK2000 motherboard. The
DS26401DK comes complete with a DS26401 octal framer, two DS21448 quad LIUs, transformers,
termination resistors, network connectors, and motherboard connectors. The DK101/DK2000 motherboard and the Dallas’ ChipView software give
point-and-click access to configurations and status
registers from a Windows�-based PC. On-board
LEDs indicate loss-of-signal, loss-of-frame, and interrupt status.
Each DS26401DK is shipped with a free DK101 motherboard. For complex applications, the DK2000
high-performance demo kit motherboard can be purchased separately.

QUICK SETUP (REGISTER VIEW) Connect DS26401DK to DK101 motherboard. Connect serial cable to a PC and DK101. Power DK101 with 3.3V. Load ChipView software. Select COM port. Select Register View. For T1 applications, load the 401_global_t1_DS26401DC.def file. For E1 applications, load the
401_global_e1_DS26401DC.def file. Make sure that all the register settings are correct for the proper function desired for the DS26401DK.
Please refer to the DS26401 data sheet (/DS26401) and the DS21448 data sheet
(/DS21448) for all questions pertaining to device functionality.
ADDRESS MAP DK101 daughter card address space begins at 0x81000000. DK2000 daughter card address space begins at: 0x30000000 for slot 0
0x40000000 for slot 1
0x50000000 for slot 2 0x60000000 for slot 3 All offsets given below are relative to the beginning of the daughter card address space.
