MC100EP139DW

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100EP139DW is a clock generator integrated circuit manufactured by onsemi, belonging to the 100EP ECL logic family. It operates within a supply voltage range of 3V to 5.5V and supports differential NECL and PECL inputs with differential ECL outputs. The device provides a 1:4 input-to-output ratio and features a maximum frequency of 1GHz. Packaged in a 20-TSSOP surface-mount format, it functions as a clock divider/multiplier without an internal PLL. The component is rated for operation between -40°C and +85°C and has been designated as obsolete.
