MC100H644 Overview
DRIVER • Generates Clocks for 68030/040 • Meets 68030/040 Skew Requirements • TTL or PECL Input Clock • Extra TTL and ECL Power/Ground Pins • Within Device Skew on Similar Paths is 0.5 ns • Asynchronous Reset • Single +5.0V Supply The user has a choice of using either TTL or PECL (ECL referenced to +5.0V) for the input clock. TTL clocks are typically used in present MPU systems. However, as clock speeds increase to 50MHz and beyond, the inherent superiority of ECL (particularly d
