- Low Voltage Positive Emitter Coupled Logic (LVPECL) IO is a technology-independent interface that may be designed into a variety of integrated circuit technologies. An open-drain architecture along with a programmable steering current allows different system implementations. The interface may be run at 3.3V or 2.5V to allow further system flexibility and several common mode requirements. The LVPECL interface is intended to operate at frequencies up to 750MHz (1.5Gbps). LVPECL is interoperable with other standards, such as HSTL, LVDS, and CML. This IO may be also AC coupled into DC-balanced systems to accommodate different common mode requirements. Multiple steering currents enable adjustable differential signaling levels, which are needed for power and noise margin optimization. When properly terminated, the constant driver current produces a fixed current in the link as well as the driver, which in turn simplifies system design by eliminating supply switching current surges.
