Key Parameters

Substitute Part Grouping Explanation

Substitution of the CY22393FXAT is determined by strict equivalence across the following critical parameters:

• Frequency specification (166MHz maximum)
• Input/Output configuration (LVTTL/Crystal input, CMOS output)
• Circuit count and distribution ratio (1 circuit, 1:6 ratio)
• PLL architecture (with bypass capability)
• Supply voltage range (3.135V ~ 3.465V)
• Package type (16-TSSOP surface mount)
• Temperature operating range (-40°C ~ 85°C)
• Compliance certifications (ROHS3, AEC-Q100)

The CY22393FXIT qualifies as a parametric equivalent based on identical electrical specifications and package configuration. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The CY22393FXIT is the direct active equivalent for the obsolete CY22393FXAT. Both parts share identical electrical and mechanical specifications, including automotive-grade qualification (AEC-Q100) and ROHS3 compliance. The CY22393FXIT maintains active product status with higher inventory availability, making it the appropriate selection for new designs and ongoing production requirements. The packaging format difference (Tape & Reel versus Tube) reflects standard distribution practices and does not affect functional compatibility or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can CY22393FXIT be used as a direct replacement for CY22393FXAT?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including frequency, input/output configuration, supply voltage, temperature range, and package dimensions. The CY22393FXIT is the active production equivalent.

Q: What is the significance of the product status difference?

A: The CY22393FXAT is classified as Obsolete, indicating discontinued manufacturing and limited availability. The CY22393FXIT maintains Active status with ongoing production and higher inventory levels, ensuring supply chain continuity.

Q: Does the Tape & Reel packaging of CY22393FXIT affect compatibility?

A: No. Tape & Reel is a standard distribution format for high-volume production and does not alter electrical performance or physical package dimensions. The 16-TSSOP package footprint remains identical.

Q: Are both parts qualified for automotive applications?

A: Yes. Both CY22393FXAT and CY22393FXIT carry Automotive grade classification with AEC-Q100 qualification, meeting automotive industry reliability and quality standards.

Q: What are the critical parameters for substitution compatibility?

A: Substitution is valid when the following parameters match: maximum frequency (166MHz), input type (LVTTL/Crystal), output type (CMOS), circuit count (1), distribution ratio (1:6), supply voltage range (3.135V ~ 3.465V), operating temperature range (-40°C ~ 85°C), and package type (16-TSSOP surface mount).
