2308-2HPGG

Overview

The Renesas Electronics Corporation 2308-2HPGG is a 3.3V Zero Delay Clock Multiplier designed for high-speed clock distribution and multiplication applications. Operating within a frequency range of 10 MHz to 133 MHz, it utilizes a Phase-Lock Loop (PLL) architecture to achieve zero delay by aligning the phase between the incoming clock and output clocks. The device features eight outputs organized into two banks of four, allowing for separate enable control. It supports 2x and 4x multiplication ratios and requires no external RC network. The component operates at 3.3V VDD and is characterized for commercial temperature ranges.

Feature Summary

• Zero Delay Buffer: Synchronizes outputs to the input clock using an external feedback pin to minimize skew.
• Output Configuration: Distributes one clock input to two banks of four LVCMOS outputs with individual bank enables.
• Multiplication Options: Supports 2x and 4x prescaling and multiplication of the input reference clock.
• Low Jitter Performance: Delivers cycle-to-cycle jitter less than 200 ps and output skew under 200 ps.

Applications

• High-speed clock distribution in digital systems.
• Clock multiplication for processors and memory interfaces.
• System testing via direct input clock drive mode.

Part Context

The 2308 series belongs to Renesas Electronics' timing product portfolio, which has been acquired by SiTime. While datasheets remain available on Renesas.com until the end of 2026, new design-in support and procurement inquiries are directed to SiTime. The 2308-2HPGG specifically denotes the 2x/4x multiplier variant in the TSSOP-16 package.

Replacement Considerations

Publicly confirmed substitute part numbers for the 2308-2HPGG are not provided in the source material. Users should consult SiTime or Renesas technical resources for current alternative recommendations following the acquisition transition.
