2 Component Suppliers SUPPLIER PHONE FAX Digi-Key Coilcraft Murata AVX Note: Please indicate that you are using the MAX3747/MAX3474A when ordering from these suppliers. Quick Start 1) Shunt the center pin of JU1 to TP3 to connect DISABLE to LOS. 2) Shunt the center pin of JU2 to 4.75kΩ. Shunt the center pin of JU3 to VCC. This terminates LOS to VCC through a 4.75kΩ resistor. 3) Turn all positions of the dipswitch (U2) off. Turn the 4 and 5 switch to on. This sets the minimum LOS threshold. Detailed Description Dipswitch The dipswitch allows for quick setting of various threshold levels. When only switch 4 and 5 are turned on, the MAX3747/MAX3747A are set to the low threshold level. Switch 3 and 6 sets to the medium threshold level, and switch 2 and 7 sets to the high threshold level. Switch 1 and 8 connect the potentiometer allowing the user to set any threshold level. Jumper JU1 Jumper JU1 allows the user to connect the DISABLE pin to LOS, VCC, or GND Jumper JU2 Jumper JU2 allows the user to terminate the LOS output to 4.75kΩ or 10.0kΩ. Jumper JU3 Jumper JU3 connects the LOS termination resistor or to a separate supply connected to TP4. 4) Connect a +3.3V supply to VCC (J10). Connect the power supply ground to J11 (GND). 5) Connect a 100mV P-P 2.125Gbps signal to J1 (IN+) and J2 (IN-) 6) Connect J3 (OUT+) and J4 (OUT-) to a 50Ω highspeed oscilloscope. The differential output of the MAX3747 should be 500mV P-P. The differential output of the MAX3747A should be 800mV P-P. 2.
