WebThe LVPECL driving the FPGA is a 3.3V one. My questions: 1. How does the input stage of the FPGA look like when defined as LVPECL? 2. Is an external termination required, or is it there inside the FPGA input stage? 3. Should I use the "50ohm to Vcc-2V" termination on the FPGA inputs with DC coupling? 4.

The Free Dictionary WebThis locates it to pin L15, where the oscillator is connected to the FPGA on the board. It then tells the toolchain the clock frequency of 100 MHz with a timing constraint. The pin also needs to be sent through an IBUFG and BUFG before you can use it, like so:

WebLVPECL is a differential I/O standard that requires a pair of signal lines for each channel. The differential transmission scheme is less susceptible to common-mode noise than single-ended transmission methods. LVPECL standards require external termination resistors to reduce signal reflection.
