Overview
The ZL40208LDG1 is a clock buffer manufactured by Microchip Technology, designed for high-speed signal distribution. It features a 2:6 input-to-output ratio with LVPECL outputs and includes external termination capabilities. The device operates within a supply voltage range of 2.375V to 3.465V and supports a maximum frequency of 750 MHz. It is housed in a 32-VFQFN package with an exposed pad, suitable for surface-mount applications across a temperature range of -40°C to +85°C.
Feature Summary
- 2:6 fanout buffer configuration with LVPECL outputs
- Supports external termination for impedance matching
- Maximum operating frequency of 750 MHz
- Operates on a single 2.375V to 3.465V supply
Applications
- High-speed data communication systems requiring clock distribution
- Test and measurement equipment needing precise timing signals
- Telecommunications infrastructure utilizing LVPECL standards
Procurement Notes
Verify the specific suffix 'LDG1' against the manufacturer's current datasheet to confirm pinout and electrical specifications match the design requirements. Ensure the 32-QFN package dimensions align with the PCB footprint. Confirm RoHS compliance status through official documentation before procurement.
Selection Notes
Select this component when a 2-input to 6-output LVPECL buffer is required. Verify that the system power supply falls within the 2.375V to 3.465V range. Consider the external termination feature if board-level impedance control is preferred over internal options. Compare against other ZL402xx series variants for different input/output ratios.
Part Context
This part belongs to the ZL402xx family of SmartBuffer clock buffers from Microchip Technology. These devices are engineered for low-jitter performance and flexible configuration in high-speed digital designs. The LDG1 suffix typically denotes a specific package type and tape/reel or tray packaging option within the product line.
Replacement Considerations
Check for direct cross-references within the ZL402xx series for alternative input/output configurations. Verify compatibility with existing layout constraints due to the 32-QFN package. Consult Microchip's official substitution guide for any updated versions or enhanced performance alternatives.
