91305AGLF

Overview

The IDT91305AGLF is a high-performance, low-skew, low-jitter zero-delay buffer designed for communication systems. It utilizes phase-locked loop (PLL) technology to align the REF input with CLKOUT signals in both phase and frequency. The device supports clock distribution at speeds from 10 MHz to 133 MHz. Key electrical characteristics include less than 125 ps cycle-to-cycle jitter and controlled skew outputs. It features 5V tolerant inputs and operates within a commercial temperature range of 0°C to +70°C. The component is available in 16-pin packages including SSOP, SOIC, and TSSOP.

Feature Summary

• Zero delay buffer using PLL technology for phase and frequency alignment
• Frequency range of 10 MHz to 133 MHz with 5V tolerant REF input
• Cycle-to-cycle jitter less than 125 ps
• Group-to-group skew less than 215 ps and within-group skew less than 100 ps

Applications

• High-speed clock distribution in communication systems
• Spread spectrum applications requiring high loop filter bandwidth
• Systems requiring precise clock alignment with low jitter

Procurement Notes

Verify the obsolete status of the 91305AGLF before procurement planning. The manufacturer recommends the 2308B as an alternative for new design and re-design activities. Confirm package availability and moisture sensitivity levels, as stock status may vary significantly for discontinued components. Ensure compatibility with existing board layouts when considering replacement options.

Selection Notes

Select this component for applications requiring zero-delay buffering within the 10-133 MHz range. Consider the 16-pin package constraints and commercial temperature limits (0°C to +70°C). Evaluate the 5V tolerant input capability against system voltage requirements. For new designs, assess the recommended 2308B successor for improved availability and feature sets.

Part Context

The 91305AGLF belongs to the IDT9130x series of high-performance communication buffers. This family is characterized by low skew and low jitter performance, utilizing PLL technology for clock alignment. The specific AG suffix indicates lead-free composition and a -40°C to +85°C temperature grade variant, although the base model documentation often cites commercial ranges. It serves as a legacy solution for clock distribution networks.

Replacement Considerations

The 2308B is the officially recommended replacement for the 91305AGLF. Designers should consult the 2308B datasheet for pinout compatibility and electrical parameter differences. The 2308B offers similar zero-delay buffering capabilities with updated manufacturing support.
