3.3V E1/T1/J1 Line Interface Design Kit Daughter Card


The DS21Q348 design kit is an evaluation board for the DS21Q348 3.3V E1/T1/J1 line interface. The DS21Q348DK is intended to be used as a daughter card with either the DK2000 or the DK101 motherboards. The board comes complete with a line interface unit (LIU), transformers, termination resistors, configuration switches, network connectors, and an interface to the motherboard.

Key Features

  • Expedites New Designs by Eliminating First-Pass Prototyping
  • Interfaces Directly to the DK101 or DK2000 Motherboards
  • Demonstrates Key Functions of the DS21Q348
  • High-Level Software Provides Visual Access to Registers
  • Software-Controlled (Register Mapped) Configuration Switches to Facilitate Clock and Signal Routing
  • BNC Connections for 75Ω E1
  • Bantam and RJ48 Connectors for 120Ω E1 and 100Ω T1
  • Multitap Transformer Facilitates True Impedance Matching for 75Ω and 120Ω /100Ω Paths
