8523CGLF

Overview

The IDT 8523CGLF is a single-circuit fanout buffer designed for clock distribution applications. It features a 2:4 input-to-output ratio, accepting differential inputs and providing four HSTL outputs. The device supports a maximum frequency of 650 MHz and operates within a supply voltage range of 3.135V to 3.465V. It accommodates various differential input levels including CML, HCSL, HSTL, LVDS, LVHSTL, LVPECL, and SSTL. The component is housed in a 20-TSSOP package with a width of 4.40mm and is rated for an operating temperature range of 0°C to 70°C.
