MC88915TEI70

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC88915TEI70 is a low skew CMOS PLL clock driver manufactured by Renesas Electronics Corporation. It features an integrated Phase-Locked Loop (PLL) and provides eight output drivers with a maximum operating frequency of 70 MHz. The device accepts TTL input signals and generates CMOS or TTL compatible outputs, supporting a 2:8 input-to-output ratio. It operates within a supply voltage range of 4.75 V to 5.25 V and is rated for industrial temperatures from -40°C to +85°C. The component is housed in a 28-lead Thin Small Outline Package (TSOP).
