DS1843K

DS1843 Evaluation Kit User Guide UG6224; Rev 0; 10/15 Below are instructions for connecting and powering the DS1843 evaluation kit. See the schematic at the end of this document for more information. 1. Connect GND, then VCC to a power supply. VCC should be between 3.0V and 5.5V. VCC is filtered on the EV kit using a 600Ω ferrite bead. 2. Jumper J6 is provided to switch DEN (differential output enable) between VCC and GND to select single-ended or differential output. If DEN is connected to GND, then single- ended output is enabled. Jumper DEN to VCC for differential output. 3. A BNC jack is provided for the SEN (sample enable) input. A 50Ω termination to ground (R5) is included on the EV kit board. Apply a pulse of 300ns or greater to this input. Ensure that the pulse generator is set up with a 50Ω series resistance. 4. Inputs VINP and VINN are connected to BNC jacks. Several footprints have been provided so the loading applied to the inputs can be changed. This EV kit is shipped configured for a current-source input with a 1.6kΩ resistor between VINP and VINN. VINN can be connected to GND using the jumper J7 “VINNGND.” 5. The outputs VOUTP and VOUTN are also connected to BNC jacks. Again, several footprints have been included to add loading to these outputs. This kit is shipped with no loading applied to the two output pins. 6. All optional components use 0805 footprints. The Spare Components section of the board contains some optional components that can be used to load either the inputs or the outputs of the DS1843. ©2015 by Maxim Integrated Products, Inc.
