IDT2308A-1HPGI

Clock Generators, PLLs, Frequency Synthesizers Overview

The IDT2308A-1HPGI is a 3.3V Zero Delay Clock Multiplier manufactured by Renesas Electronics Corporation, formerly part of the Integrated Device Technology (IDT) portfolio. This component functions as a high-speed phase-lock loop (PLL) clock multiplier designed for applications operating within a frequency range of 10MHz to 133MHz. It features a 1:8 input-to-output ratio and utilizes LVTTL/LVCMOS signaling standards for both input and output interfaces. The device is housed in a 16-TSSOP package with a width of 4.40mm. Key electrical specifications include a maximum operating frequency of 133.3MHz and a supply voltage range of 3V to 3.6V.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero Delay Buffer architecture aligns output phase with the incoming clock input.
• Supports 1x multiplication ratio with 8 LVCMOS outputs distributed across two banks.
• Low jitter performance with cycle-to-cycle jitter typically under 200ps.
• External feedback pin allows synchronization of outputs to the clock input.

Clock Generators, PLLs, Frequency Synthesizers Applications

• High-speed clock distribution in communication systems.
• Clock multiplication and buffering for digital logic circuits.
• System timing reference generation for processors and memory interfaces.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

This component is classified as obsolete or not recommended for new designs. Verification of current stock availability from authorized distributors is required before procurement. Alternative components such as the CDCVF25081 series may be considered for replacement strategies. Ensure compliance with RoHS status details provided in official datasheets, as legacy parts may have varying environmental certifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a zero-delay buffer with 1:8 fan-out is required at frequencies up to 133MHz. Verify that the system operates within the 3V to 3.6V supply range and requires LVTTL/LVCMOS compatible I/O levels. Consider the 16-TSSOP package constraints for PCB layout. Evaluate alternative modern equivalents if long-term supply assurance is critical for the product lifecycle.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The IDT2308A-1HPGI belongs to the IDT 2308 family of PLL-based clock multipliers. This family includes variants with different multiplication ratios (1x, 2x, 4x) and drive strengths. The 'A' suffix often denotes specific process or revision updates within the IDT/Renesas lineage. The device is part of Renesas's broader timing solutions portfolio, which has seen organizational transitions involving SiTime.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Publicly documented upgrade alternatives include the Texas Instruments CDCVF25081PW and CDCVF25081PWR. These devices offer similar zero-delay buffer functionality and are listed as direct upgrades in distributor catalogs. Verify pin compatibility and electrical parameters against the original design requirements before substitution.
