ZL40219LDG1 Equivalent & Substitute Parts

Part Overview

The ZL40219LDG1 is a Clock Fanout Buffer (Distribution) IC manufactured by Microchip Technology, designed for high-speed clock distribution applications. This 1:8 differential clock buffer operates at frequencies up to 750 MHz and supports multiple input signal types (CML, HCSL, LVCMOS, LVDS, LVPECL) with LVDS output. The device is housed in a 32-VFQFN Exposed Pad package and is currently in active production status. Substitute parts may be required due to inventory constraints, design flexibility needs, or application-specific output channel requirements.

Substitute Part Grouping Explanation

Substitute parts for the ZL40219LDG1 are qualified based on the following criteria:

Matching Parameters (Required for Substitution):

• Manufacturer: Microchip Technology
• Package / Case: 32-VFQFN Exposed Pad
• Mounting Type: Surface Mount
• Differential - Input:Output: Yes/Yes
• Input Signal Types: CML, HCSL, LVCMOS, LVDS, LVPECL
• Output Signal Type: LVDS
• Frequency - Max: 750 MHz
• Voltage - Supply: 2.375V ~ 3.465V
• Operating Temperature: -40°C ~ 85°C
• Product Status: Active
• RoHS Status: ROHS3 Compliant
• MSL Rating: 3 (168 Hours)

Variable Parameter (Allows Substitution):

• Ratio - Input:Output: The ZL40219LDG1 features a 1:8 configuration. Substitute parts with 1:6 output ratios (ZL40216LDG1, ZL40217LDG1) are functionally equivalent for applications requiring fewer output channels, provided the circuit design accommodates the reduced channel count.

Parameter Comparison

Engineering Selection Recommendations

All three parts (ZL40219LDG1, ZL40216LDG1, ZL40217LDG1) maintain active production status and full ROHS3 compliance. Selection between these devices depends on output channel requirements:

ZL40219LDG1 is the primary choice for applications requiring eight differential output channels at 750 MHz with multi-format input support.

ZL40216LDG1 and ZL40217LDG1 are functionally equivalent alternatives when six output channels satisfy application requirements. Both substitute parts share identical electrical specifications, package geometry, and compliance certifications with the main part. The choice between ZL40216LDG1 and ZL40217LDG1 is determined by inventory availability and procurement lead times.

Frequently Asked Questions (FAQ)

Q: Can ZL40216LDG1 or ZL40217LDG1 directly replace ZL40219LDG1 in existing designs?

A: Direct replacement is possible only if the circuit design uses six or fewer output channels. The 1:6 ratio devices are pin-compatible within the 32-VFQFN package but provide two fewer output channels. PCB layout and signal routing must accommodate the reduced channel count.

Q: Are there electrical performance differences between the three parts?

A: No. All three devices operate at identical maximum frequency (750 MHz), supply voltage range (2.375V ~ 3.465V), and temperature specifications (-40°C ~ 85°C). The only difference is the output channel ratio.

Q: Do all three parts support the same input signal formats?

A: Yes. ZL40219LDG1, ZL40216LDG1, and ZL40217LDG1 all accept CML, HCSL, LVCMOS, LVDS, and LVPECL input signals and output LVDS.

Q: What is the difference between ZL40216LDG1 and ZL40217LDG1?

A: Both parts are electrically and mechanically identical with 1:6 output ratios. They are interchangeable substitutes for each other. Selection is based on inventory availability and supplier lead times.

Q: Are moisture sensitivity and RoHS compliance identical across all three parts?

A: Yes. All three parts carry MSL rating 3 (168 Hours) and ROHS3 compliance status.
