Differential LVPECL (Low-Voltage Positive Emitter-Coupled Logic)
LVPECL Transceiver Termination
LVPECL is a very popular and powerful high-speed interface in many system applications.
Virtex-5 FPGA I/Os are designed to comply with the EIA/TIA electrical specifications for
2.5V LVPECL to make system and board design easier.
The Virtex-5 FPGA LVPECL transmitter and receiver requires the termination shown in
Figure
50 Ω transmission lines. The LVPECL driver is composed of two LVCMOS drivers that
form a compliant LVPECL output when combined with the three resistor output
termination circuit.
