2308-1HPGGI

Overview

The Renesas Electronics 2308-1HPGGI is a discontinued 3.3V Zero Delay Clock Multiplier designed for high-speed clock distribution and multiplication applications. It utilizes a Phase-Lock Loop (PLL) to align the phase between incoming and output clocks, operating within a frequency range of 10 MHz to 133 MHz. The device features eight LVCMOS outputs organized into two banks of four, with independent enable controls. Key electrical specifications include an output skew of less than 200 ps, cycle-to-cycle jitter under 200 ps, and a maximum operating supply current of 70 mA at 3.3 V. It is housed in a TSSOP-16 package.

Feature Summary

• Zero delay PLL architecture synchronizes output phase with input clock
• Eight LVCMOS outputs distributed across two independently enabled banks
• Low jitter performance with cycle-to-cycle jitter <200 ps
• External feedback pin allows user-controlled delay adjustment

Applications

• High-speed clock distribution networks
• System synchronization requiring zero delay alignment
• Test mode operation via direct input clock drive

Procurement Notes

The 2308-1HPGGI is officially listed as End-of-Life (EOL) by Renesas Electronics. Availability is restricted to existing stock or secondary market sources. Verification of component authenticity and storage history is critical due to the discontinued status. Distributors may list obsolete inventory without guaranteed lead times or warranty coverage.

Selection Notes

This component supports 1x multiplication ratios. For designs requiring 2x or 4x multiplication, alternative variants such as the IDT2308-2 or IDT2308-3 are required. The external feedback configuration necessitates careful PCB layout to maintain signal integrity. Ensure the application operates within the specified -40°C to +85°C temperature range.

Part Context

The 2308 series belongs to the IDT/Renesas family of zero-delay buffers and multipliers. The 'H' suffix typically denotes high-drive capability, while 'GGI' specifies the TSSOP-16 package with industrial temperature rating. This part represents the legacy IDT product line acquired by Renesas.

Replacement Considerations

Direct functional substitutes include IDT2308-1DCG, IDT2308-1DCI, and IDT2308-1SPGI. These parts share the same core functionality but differ in package type (SOIC vs. TSSOP) or temperature grade. Verify pin compatibility before substitution.
