IDT2308-5HPGI

Clock Generators, PLLs, Frequency Synthesizers Overview

The IDT2308-5HPGI is a high-speed phase-lock loop (PLL) clock multiplier manufactured by Renesas Electronics Corporation. It operates within the 10MHz to 133.3MHz frequency range and provides a 1:8 ratio with one input and eight outputs. The device features a 3.3V supply voltage, LVTTL input/output types, and a 16-TSSOP package. It supports commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges. Key electrical parameters include output skew under 200 ps and cycle-to-cycle jitter under 200 ps at 66.67 MHz.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component authenticity through authorized channels as the product line has undergone corporate transitions. Confirm RoHS compliance status, noting that specific ordering suffixes may indicate lead-free configurations. Ensure the selected variant matches the required operating temperature range for the intended application environment.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the IDT2308-5HPGI when a divide-by-two output configuration is required alongside high drive strength. The 'I' suffix indicates suitability for industrial temperature ranges up to +85°C. Verify load capacitance requirements against the switching characteristics tables to ensure timing specifications are met at the target operating frequency.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the IDT2308 family of zero-delay clock multipliers. The manufacturer's clock business was acquired by SiTime, which continues to provide documentation and support for existing products until the end of 2026. The part represents a legacy solution for high-speed clock distribution in communication and computing systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Public confirmed substitute part numbers include CDCVF25081PW and CDCVF25081PWR from Texas Instruments. These alternatives offer similar zero-delay buffering capabilities and should be evaluated for pin compatibility and electrical performance matching.
