2308B-4DCG8

Overview

The Renesas 2308B-4DCG8 is a high-speed phase-lock loop (PLL) clock multiplier designed for zero-delay clock distribution. It operates within an input frequency range of 10 MHz to 133.3 MHz, providing a fixed 4x multiplication ratio. The device features two banks of four LVCMOS outputs each, controlled via select addresses. Key electrical parameters include a maximum cycle-to-cycle jitter of 100 ps and output skew less than 200 ps. It functions on a single 3.3V supply voltage and is housed in a 16-pin SOIC package.

Feature Summary

• Zero-delay PLL architecture synchronizes output phase with the input clock reference.
• Fixed 4x multiplication ratio for generating higher frequency clocks from lower frequency references.
• Dual output bank configuration allows independent tri-stating of eight total outputs.
• Low jitter performance with cycle-to-cycle jitter capped at 100 ps.

Applications

• High-speed clock distribution networks requiring precise phase alignment.
• System synchronization where external feedback loops are utilized to control delay.
• Test mode applications allowing direct input clock drive to outputs for verification.

Part Context
