IDT23S08-1HPG8

Clock Generators, PLLs, Frequency Synthesizers Overview

The IDT23S08-1HPG8 is a discontinued high-speed phase-lock loop (PLL) clock multiplier manufactured by Renesas Electronics Corporation. It functions as a zero-delay buffer, aligning the phase between incoming and output clocks to eliminate propagation delay. The device accepts a single LVCMOS input signal within a frequency range of 10 MHz to 200 MHz and distributes it to eight outputs organized into two banks of four. It operates on a 3.3V supply voltage and supports spread spectrum input compatibility. The component is housed in a 16-pin TSSOP package with a width of 4.40 mm.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero-delay buffering achieved by synchronizing output phases to the input clock reference.
• Supports input frequencies from 10 MHz to 200 MHz with 1x multiplication ratio.
• Features spread spectrum input compatibility for EMI reduction.
• Includes power-down mode drawing less than 12µA when no input clock is present.

Clock Generators, PLLs, Frequency Synthesizers Applications

• High-speed clock distribution systems requiring precise phase alignment.
• Spread spectrum clock generation for electromagnetic interference mitigation.
• System testing modes where direct input clock driving of outputs is required.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the IDT23S08 family of PLL clock multipliers. The suffix '1H' indicates a specific configuration variant within this series, typically denoting high-drive capabilities or specific pinout characteristics compared to standard variants. The 'PG8' suffix identifies the specific tape and reel packaging format for the 16-TSSOP package.
