IDT2309B-1HPGGI

Clock Generators, PLLs, Frequency Synthesizers Overview

The IDT2309B-1HPGGI is a low phase noise, high-speed PLL-based clock buffer manufactured by Renesas Electronics Corporation. It operates at 3.3V and provides nine low-skew outputs with frequencies up to 133 MHz. The device utilizes proprietary low jitter PLL techniques to achieve zero delay buffering, synchronizing outputs directly to the input clock. It is housed in a 16-pin TSSOP package and supports an operating temperature range of -40°C to 85°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero delay buffer architecture using PLL technology for minimal output skew
• Nine LV TTL compatible outputs supporting frequencies up to 133.33 MHz
• Low power consumption suitable for mobile and desktop PC applications
• Multiple VDD and VSS pins designed for noise and EMI reduction

Clock Generators, PLLs, Frequency Synthesizers Applications

• Clock distribution in mobile PC systems
• Clock distribution in desktop PC systems with SDRAM
• Buffering clocks for two DIMMs or four SO-DIMMs
• Feedback generation for external or chipset PLLs

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the manufacturer designation as Renesas Electronics Corporation, reflecting the acquisition of IDT. Confirm the specific suffix '1HPGGI' corresponds to the TSSOP-16 package and industrial temperature grade. Check current product status, as some variants in the 2309 series may have different lifecycle statuses.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single clock source needs to drive nine loads with strict skew requirements. Ensure the system requires 3.3V operation and LV TTL output levels. Verify that the 133 MHz maximum frequency meets the target bus speed requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the 2309 series of clock buffers. It is functionally similar to the IDT2309NZ but includes specific packaging and performance suffixes. The device is distinct from the 2308 series, which functions as a clock multiplier rather than a pure buffer.
