Parameter Comparison

Engineering Selection Recommendations

Both the AD9518-3ABCPZ-RL7 and AD9518-4ABCPZ-RL7 maintain Active product status with identical RoHS3 compliance and REACH unaffected certifications. Selection between these parts is determined by application frequency requirements. The AD9518-3ABCPZ-RL7 supports maximum input frequencies to 2.25GHz, while the AD9518-4ABCPZ-RL7 operates to 1.8GHz maximum. Both parts share identical supply voltage ranges, operating temperature specifications, and package footprints, ensuring direct PCB-level compatibility when frequency specifications align with system requirements. Component selection should be based on the maximum input clock frequency required by the end application.

Frequently Asked Questions (FAQ)

Q: Can AD9518-4ABCPZ-RL7 be used as a direct replacement for AD9518-3ABCPZ-RL7?

A: Direct substitution is possible only when the application maximum input frequency requirement does not exceed 1.8GHz. The AD9518-4ABCPZ-RL7 is rated to 1.8GHz maximum, compared to 2.25GHz for the AD9518-3ABCPZ-RL7. All other electrical and mechanical parameters are identical.

Q: Are the package footprints identical between these parts?

A: Yes. Both parts use the 48-VFQFN Exposed Pad, CSP package with supplier device package designation 48-LFCSP-VQ (7x7). PCB layout and assembly processes are interchangeable.

Q: Do these parts have the same supply voltage requirements?

A: Yes. Both parts operate within the identical supply voltage range of 3.135V to 3.465V and share the same operating temperature range of -40°C to 85°C.

Q: What is the significance of the frequency difference between these parts?

A: The frequency specification indicates the maximum input clock frequency each device can accept. Applications requiring input frequencies above 1.8GHz must use the AD9518-3ABCPZ-RL7. Applications with lower frequency requirements may use either part.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the AD9518-3ABCPZ-RL7 and AD9518-4ABCPZ-RL7 are ROHS3 compliant with Moisture Sensitivity Level 3 (168 Hours).
