Engineering Selection Recommendations

The CY2309ZXC-1HT is the primary substitute for the CY23S09ZXC-1HT. Both devices share identical electrical specifications, including maximum frequency (133.33MHz), input-to-output ratio (1:9), supply voltage range (3V ~ 3.6V), and operating temperature range (0°C ~ 70°C). The CY2309ZXC-1HT maintains Active product status, ensuring continued availability and support. Both parts are ROHS3 Compliant with identical MSL ratings and packaging specifications.

The CY2308ZXC-1HT is a secondary substitute option. This device differs in input-to-output ratio (1:8 versus 1:9) and operates at 133.3MHz versus 133.33MHz. The CY2308ZXC-1HT is suitable for applications where an 8-output fanout configuration is acceptable and frequency tolerance permits the minor frequency difference. This part also maintains Active product status and identical compliance certifications.

Selection between CY2309ZXC-1HT and CY2308ZXC-1HT depends on circuit requirements for output channel count and frequency specifications. Both parts satisfy identical supply voltage, temperature, packaging, and regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the CY2309ZXC-1HT directly replace the CY23S09ZXC-1HT?

A: Yes. The CY2309ZXC-1HT is a direct substitute. Both devices feature identical input-to-output ratio (1:9), maximum frequency (133.33MHz), supply voltage range (3V ~ 3.6V), operating temperature range (0°C ~ 70°C), and 16-TSSOP packaging. All electrical and mechanical parameters are equivalent.

Q: What is the difference between the CY2308ZXC-1HT and CY2309ZXC-1HT?

A: The primary difference is the input-to-output ratio. The CY2308ZXC-1HT provides 1:8 fanout (8 outputs), while the CY2309ZXC-1HT provides 1:9 fanout (9 outputs). The CY2308ZXC-1HT operates at 133.3MHz compared to 133.33MHz for the CY2309ZXC-1HT.
