IDT2308A-1HDC

Clock Generators, PLLs, Frequency Synthesizers Overview

The IDT2308A-1HDC is a high-speed phase-lock loop (PLL) clock multiplier manufactured by Renesas Electronics Corporation. It functions as a zero-delay buffer, distributing one clock input to two banks of four outputs each. The device operates within a frequency range of 10MHz to 133MHz and utilizes an external feedback pin to synchronize outputs with the input clock. Key electrical specifications include a supply voltage of 3.3V, output skew of less than 200 ps, and cycle-to-cycle jitter under 200 ps. The component is housed in a 16-pin SOIC package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero-delay buffer architecture aligns output phase with the REF input using PLL technology
