PECL and HSTL are two of the high-speed interface standards in common use. PECL (positive supply referred ECL) is an older standard than HSTL and was developed as a higher speed alternative to the TTL logic standards. HSTL was defined as an interface standard for digital integrated circuits. The two standards are not directly compatible. Some PE……
