Overview
The 8INT31H800ANLGI8 is an 8-output very low phase jitter HCSL fanout buffer designed for high-performance interconnect applications. It operates at frequencies up to 350MHz and supports DB800H requirements with extremely low additive phase jitter of 65fs typical. The device features a universal differential input compatible with HCSL or LVPECL sources, four output enable pins controlling pairs, and a space-saving 32-pin VFQFN package.
Feature Summary
- Eight HCSL differential output pairs
- Extremely low RMS additive phase jitter (65fs typical)
- Universal differential input supporting HCSL and LVPECL
- Four OE pins for independent output control
Applications
- DB800H compliant clock distribution
- High-speed Ethernet frequency generation
- CPU socket clock management
Procurement Notes
Verify the NLGI8 suffix indicates tape and reel packaging for automated assembly. Confirm the -40°C to 85°C industrial temperature range matches system requirements. Ensure the lead-free RoHS compliance aligns with environmental regulations.
Selection Notes
Select this component when ultra-low jitter is critical for signal integrity in high-speed digital interfaces. The 32-pin VFQFN package is suitable for space-constrained designs requiring minimal board area compared to larger packages.
Part Context
This part belongs to the IDT 8INT31H800A family of HCSL fanout buffers. The 'NLGI8' suffix specifically denotes the 32-lead VFQFN package configuration supplied in tape and reel format, distinguishing it from tray-packaged variants.
Replacement Considerations
Direct replacements within the same family include the 8INT31H800ANLGI, which shares identical electrical specifications but is packaged in trays instead of tape and reel.
FAQ
What is the maximum operating frequency?
The device supports operating frequencies up to 350MHz.
How are the outputs controlled?
There are four OE pins (vOE_01#, vOE_23#, vOE_45#, vOE_67#), each controlling two specific output pairs.
What input signal types are supported?
The universal differential input accepts HCSL, LVPECL, and LVHSTL signals.
