IDT2308A-1HPG

Clock Generators, PLLs, Frequency Synthesizers Overview

The IDT2308A-1HPG 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 133.3MHz and supports LVTTL input and output logic levels. Powered by a single 3V to 3.6V supply, it features an external feedback pin for synchronization, achieving output skew and cycle-to-cycle jitter below 200 ps. The component is housed in a 16-TSSOP package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero-delay PLL clock distribution with 1:8 ratio

Clock Generators, PLLs, Frequency Synthesizers Applications

• High-speed clock distribution networks
• System synchronization requiring low skew
• Digital signal processing equipment

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the part status carefully, as the IDT2308 family has been discontinued by Renesas. Confirm that the specific suffix 'A' does not indicate a non-standard variant lacking public datasheet support. Check RoHS compliance status, as older revisions may not meet current environmental regulations. Ensure the source document explicitly identifies the manufacturer as Renesas or IDT.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed 1x multiplication factor is required for frequencies up to 133.3MHz. The external feedback configuration allows control over delay between input and output clocks. Verify that the LVTTL interface compatibility matches the system's voltage levels. Consider the 16-TSSOP package dimensions if board space is constrained.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The IDT2308 series belongs to the IDT clock generator portfolio, which was acquired by Renesas Electronics. The product line includes variants with different multiplication factors (1x, 2x, 4x). The IDT2308A-1HPG specifically denotes the 1x multiplier version in the TSSOP-16 package. This family addresses high-speed clock distribution needs in commercial and industrial applications.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Public records list CDCVF25081PW and CDCVF25081PWR from Texas Instruments as upgrade alternatives. These devices offer similar zero-delay buffering capabilities. Verify pinout compatibility and electrical specifications before substitution.
