2308-1HPGG8

Overview

The Renesas Electronics Corporation 2308-1HPGG8 is a 3.3V PLL zero delay clock multiplier designed for high-speed clock distribution and multiplication applications. Operating within a frequency range of 10MHz to 133MHz, it distributes one clock input to two banks of four outputs. The device achieves zero delay by synchronizing outputs to the clock input via an external feedback pin. It features low jitter of less than 200 ps cycle-to-cycle and output skew under 200 ps. The component operates at 3.3V VDD and is available in a TSSOP-16 package.

Feature Summary

• Zero delay phase-lock loop clock distribution with external feedback synchronization
• Distributes one input clock to eight outputs across two independent banks
• Low jitter performance: <200 ps cycle-to-cycle
• Output skew specification: <200 ps

Applications

• High-speed clock distribution networks
• Clock multiplication systems requiring precise phase alignment
• Digital logic circuits operating between 10MHz and 133MHz

Procurement Notes

Verify the specific suffix 'G8' against official Renesas documentation to confirm package type and temperature range. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Check for end-of-life notices or obsolescence announcements prior to procurement planning.

Selection Notes

Select this component when a single reference clock must be multiplied and distributed to multiple synchronous loads with minimal skew. Ensure the application requires the 1x multiplication factor associated with the -1 variant. Verify that the TSSOP-16 package fits the PCB layout constraints and that the 3.3V supply voltage matches the system design.

Part Context

This part belongs to the IDT/Renesas 2308 series of zero delay clock multipliers. The series includes variants with different multiplication factors (1x, 2x, 4x) and drive strengths. The 2308-1HPGG8 specifically denotes the 1x multiplication option in a TSSOP-16 package, distinguishing it from SOIC packages or higher multiplication variants like the 2308-2 or 2308-3.

Replacement Considerations

Direct replacements include other 2308 series parts such as 2308-1HPGGI or 2308B-1HPGG8 if package and electrical parameters match. Verify that substitute components maintain the same 1x multiplication ratio and TSSOP-16 footprint.
