ZL40220LDG1

Overview

The ZL40220LDG1 is a clock fanout buffer from the Microchip ZL402x family, designed for low skew and ultra-low additive jitter performance. It features a 1:6 input-to-output ratio with LVDS output types. The device supports multiple differential input formats including CML, HCSL, LVCMOS, LVDS, and LVPECL. It operates within a supply voltage range of 2.375V to 3.465V and supports maximum frequencies up to 750 MHz. The component is housed in a 32-VFQFN package with exposed pad and functions across an industrial temperature range of -40°C to 85°C.

Feature Summary

• 1:6 Fanout Ratio: Provides one input to six outputs configuration for clock distribution.
• LVDS Outputs: Features Low Voltage Differential Signaling outputs for high-speed integrity.
• Multi-Format Input Support: Accepts CML, HCSL, LVCMOS, LVDS, and LVPECL inputs.
• Low Jitter Performance: Engineered for low skew and ultra-low additive jitter applications.

Applications

• High-speed data converter clock distribution
• Telecommunications equipment timing
• Industrial automation control systems

Procurement Notes

Verify the specific suffix 'LDG1' against the manufacturer's current datasheet to confirm pinout compatibility and packaging details. Ensure that the design accommodates the 32-VFQFN thermal requirements and the specified 2.375V to 3.465V power supply rails. Cross-reference the latest product change notifications for any marking or assembly updates.

Selection Notes

Select this component when a 1:6 fanout with LVDS outputs is required. Compare against other ZL402x variants if different ratios (e.g., 2:6 or 2:8) or output types (LVPECL) are needed. Verify that the 750 MHz maximum frequency meets the system clock requirements and that the operating temperature range aligns with the environmental conditions.

Part Context

The ZL40220LDG1 belongs to the ZL402x series of miClock fanout buffers. This family includes various configurations such as the ZL40221 (2:6) and ZL40222 (2:8). These devices are often used in conjunction with miClockSynth synthesizers to create complete, low-cost clock trees with simplified designs.

Replacement Considerations

Direct replacements within the same family include the ZL40221LDG1 (2:6 ratio) or ZL40222LDG1 (2:8 ratio), though the fanout ratio differs. For identical 1:6 LVDS specifications, verify availability of other 1:6 variants in the ZL402x lineup. Ensure functional equivalence regarding input format support and electrical parameters before substitution.
