ZL40222LDG1

Overview

The ZL40222LDG1 is a clock buffer manufactured by Microchip Technology, designed for high-speed signal distribution. It functions as a 2:8 LVDS fanout buffer with external termination capabilities. The device supports a maximum frequency of 750 MHz and operates within a supply voltage range of 2.375V to 3.465V. It accepts multiple input formats including CML, HCSL, LVCMOS, LVDS, and LVPECL, while providing differential LVDS outputs. The component is housed in a 32-QFN package (5x5 mm) and is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• 2:8 LVDS fanout buffer configuration
• Supports external termination
• Maximum frequency of 750 MHz
• Multi-format input compatibility (CML, HCSL, LVCMOS, LVDS, LVPECL)

Applications

• High-speed data acquisition systems

Procurement Notes

Verify the specific suffix LDG1 against the manufacturer's current datasheet to confirm pinout and electrical specifications. Ensure that the required external termination components are included in the bill of materials, as this feature is integral to the device's operation. Confirm availability through authorized distributors, as stock levels may vary.

Selection Notes

Select the ZL40222LDG1 when a 2-input to 8-output LVDS distribution solution is required. Consider the 750 MHz frequency limit and the need for external termination when designing the PCB layout. Compare with similar models like the ZL40221 if a different output ratio or package size is preferred.

Part Context

This component belongs to the ZL4022x series of clock buffers from Microchip Technology. These devices are engineered for low jitter and skew performance in demanding timing applications. The ZL40222 specifically addresses scenarios requiring robust LVDS signal distribution with flexible input options.

Replacement Considerations

Check for direct replacements such as the ZL40221, which offers a 2:6 ratio in the same package family. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
