2308B-1HPGGI

Overview

The Renesas Electronics Corporation 2308B-1HPGGI is a high-speed phase-lock loop (PLL) clock multiplier designed for zero-delay clock distribution applications. Operating within a frequency range of 10 MHz to 133 MHz, this device aligns the phase between the incoming clock and output clocks to eliminate propagation delay. It features two banks of four outputs each, controlled via select addresses, allowing independent tri-stating of output banks. The component operates at 3.3V VDD and utilizes a TSSOP-16 package. Key electrical specifications include a maximum cycle-to-cycle jitter of 200 ps and an output skew of 250 ps.

Feature Summary

• Zero-delay PLL architecture synchronizes outputs directly to the input clock phase
• Dual output banks with independent enable control for flexible distribution
• Low jitter performance with cycle-to-cycle jitter under 200 ps
• External feedback pin allows user-controlled delay adjustment

Applications

• High-speed clock distribution networks requiring precise phase alignment
• System synchronization where zero propagation delay is critical
• Test mode operation for direct input clock driving of outputs

Part Context

This component belongs to the 2308B series of zero-delay clock multipliers from Renesas Electronics. The part number suffix 'HPG' indicates a High Drive capability variant housed in a TSSOP-16 package, while 'GI' typically denotes lead-free and RoHS compliance. This specific configuration supports 1x multiplication ratios as indicated by the base model designation.

Replacement Considerations

For equivalent functionality, consider the 2308B-1DCG or 2308B-1DCGI variants which offer similar zero-delay characteristics but utilize SOIC-16 packaging instead of TSSOP-16. Verify pin compatibility and drive strength requirements when substituting packages.
