2308A-2DCG8

Overview

The Renesas Electronics Corporation 2308A-2DCG8 is a discontinued high-speed Phase-Lock Loop (PLL) clock multiplier designed for zero-delay clock distribution and multiplication applications. Operating within a frequency range of 10 MHz to 133 MHz, the device aligns the phase between the incoming clock and output clock to achieve zero delay. It features two banks of four outputs each, controlled via select addresses, allowing independent tri-stating of output banks. The component operates at a 3.3V supply voltage and is housed in a 16-pin SOIC package.

Feature Summary

• Zero-delay PLL architecture synchronizes output phase with input clock
• Frequency range from 10 MHz to 133 MHz
• Two independent banks of four LVCMOS outputs each
• External feedback pin allows user-controlled delay adjustment

Applications

• High-speed clock distribution systems
• Clock multiplication and prescaling circuits
• System testing modes requiring direct input-to-output drive

Part Context

The 2308A-2DCG8 belongs to the IDT 2308 family of zero-delay clock multipliers. This specific variant provides 1x and 2x multiplication options. The '8' suffix indicates tube packaging, while 'DCG' denotes the 16-pin SOIC package type. The device is characterized for commercial operation temperatures.

Replacement Considerations

The 2308A-2DCG8 is officially listed as obsolete. Potential replacements within the same family include the 2308B series or other variants like the 2308-2DCG, though functional equivalence must be verified against datasheet specifications.
