Overview
The ZL40219LDG1 is a clock buffer manufactured by Microchip Technology, designed as an LVDS fanout buffer with integrated termination. It features one input and eight outputs, supporting a maximum input frequency of 750 MHz. The device operates within a supply voltage range of 2.375 V to 3.465 V and exhibits a maximum propagation delay of 2 ns. It is housed in a QFN-32 package and functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Eight LVDS outputs for signal distribution
- Integrated termination resistors
- Maximum input frequency of 750 MHz
- QFN-32 surface mount package
Applications
- High-speed digital systems requiring clock distribution
- LVDS signal buffering and fan-out applications
- Telecommunications infrastructure equipment
Procurement Notes
Verify the specific ordering suffix 'DG1' against the manufacturer's current datasheet to confirm package type and tape/reel options. Confirm RoHS compliance status directly with the supplier documentation before procurement. Ensure ESD handling procedures are followed due to moisture sensitivity classification.
Selection Notes
Select this component when an LVDS fanout buffer with integrated termination is required for up to eight loads. Verify that the system power supply falls within the 2.375 V to 3.465 V range. Ensure the PCB layout supports the QFN-32 footprint and thermal requirements for the specified operating temperature range.
Part Context
This part belongs to the ZL402xx series of SmartBuffer devices from Microchip Technology. These components are engineered for high-performance clock distribution in data communication and networking applications. The ZL40219 variant specifically addresses LVDS output requirements with built-in termination capabilities.
Replacement Considerations
Consult Microchip Technology documentation for direct pin-to-pin replacements or functional equivalents within the ZL402xx family. Verify compatibility with existing LVDS standards and termination requirements before substituting.
