ZL40294LDG6

Overview

The ZL40294LDG6 is a 1-to-20 fanout buffer compliant with the Intel DB2000QL specification. It provides 20 low-power push-pull HCSL outputs and supports clock frequencies from 0 to 250 MHz. The device features ultra-low additive jitter, typically 14 fs in the DB2000QL band, and includes embedded series termination resistors for 85 Ω differential transmission lines. Powered by a single 3.3 V supply, it integrates an embedded Low Drop Out (LDO) voltage regulator for superior power supply noise rejection. The component operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

Fully compliant with Intel DB2000QL specification
Ultra-low additive jitter: 14 fs typical in DB2000QL band
20 low-power push-pull HCSL PCIe outputs
Embedded series termination resistors for 85 Ω differential lines

Applications

PCI Express generation 1/2/3/4/5 clock distribution
Intel QPI
Servers
Storage and Data Centers
Switches and Routers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm packaging details. The LDG6 suffix corresponds to the 80-pin GQFN package distributed in trays. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C industrial limits before procurement.

Selection Notes

Select this component when a DB2000QL-compliant buffer with 20 outputs is required. Ensure the design utilizes 85 Ω differential transmission lines to leverage the embedded termination resistors. Verify that the system power supply is stable at 3.3 V to support the internal LDO regulator and maintain the specified jitter performance.

Part Context

The ZL40294 belongs to the Microchip Technology clock buffer family designed for high-speed digital interfaces. It serves as a direct replacement or alternative to the Intel DB2000QL standard buffer. The device is part of a broader portfolio of clock management solutions intended for server and storage infrastructure applications requiring precise clock distribution.
