IDT2308A-2DC

Clock Generators, PLLs, Frequency Synthesizers Overview

The IDT2308A-2DC is a high-speed phase-lock loop (PLL) clock multiplier designed for zero-delay clock distribution. It operates within a frequency range of 10 MHz to 133 MHz and accepts LVTTL input signals. The device provides eight outputs organized into two banks of four, supporting 1x and 2x multiplication ratios. It functions at a 3.3V supply voltage with a maximum operating current of 45 mA. Key performance metrics include output skew under 200 ps and cycle-to-cycle jitter below 200 ps. The component is housed in a 16-pin SOIC package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero-delay buffer architecture aligns output phase with the REF input clock
• Dual output banks allow independent tri-stating via address pins
• External feedback pin enables synchronization control between input and outputs
• Supports power-down mode with less than 25 uA standby current

Clock Generators, PLLs, Frequency Synthesizers Applications

• High-speed clock distribution in communication systems
• System synchronization requiring low jitter and skew
• Multiplication of reference clocks for digital logic interfaces

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

This component is classified as obsolete by Renesas Electronics. Availability is restricted to existing stock or third-party distributors. Verification of RoHS compliance status and moisture sensitivity level is required prior to procurement due to the end-of-life designation.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part for applications requiring 1x or 2x clock multiplication from a 10–133 MHz source. Ensure the design accommodates the 16-SOIC package dimensions. Verify that the system requires LVTTL input compatibility and 3.3V operation before integrating this obsolete component into new designs.
