IDT2308A-2HDC8

Clock Generators, PLLs, Frequency Synthesizers Overview

The IDT2308A-2HDC8 is a high-speed phase-lock loop (PLL) clock multiplier manufactured by Renesas Electronics Corporation. It operates within a frequency range of 10 MHz to 133 MHz and utilizes a zero-delay architecture to align the phase between the incoming clock and output clock signals. The device features two banks of four outputs each, controlled via select addresses, allowing for flexible distribution configurations. It supports external feedback synchronization and offers low jitter performance with cycle-to-cycle jitter less than 200 ps. The component is available in a 16-SOIC package and is characterized for commercial operation temperatures.
