IDT2308A-5HPG

Clock Generators, PLLs, Frequency Synthesizers Overview

The IDT2308A-5HPG is a high-speed phase-lock loop (PLL) clock multiplier and zero delay buffer IC manufactured by Renesas Electronics Corporation. It operates within a frequency range of 10MHz to 133MHz, utilizing LVTTL input and output signals. The device features a 1:8 input-to-output ratio, distributing one clock signal across two banks of four outputs each. Powered by a 3V to 3.6V supply, it is housed in a 16-TSSOP surface-mount package with a width of 4.40mm. Designed for commercial operation between 0°C and 70°C, the component ensures low jitter and output skew under 200 ps.
