SL2309SC-1 Equivalent & Substitute Parts

Part Overview

The SL2309SC-1 is a 140MHz clock buffer IC manufactured by Skyworks Solutions Inc., designed for 9-channel output distribution in 3.3V systems. This device features a Phase-Locked Loop (PLL) with bypass capability and operates across the industrial temperature range of 0°C to 70°C. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SL2309SC-1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Ratio - Input:Output: 1:9
• Voltage - Supply: 3V ~ 3.6V
• Operating Temperature: 0°C ~ 70°C
• Number of Circuits: 1
• PLL Configuration: Yes with Bypass
• Mounting Type: Surface Mount
• Moisture Sensitivity Level (MSL): 3 (168 Hours)

Allowable Variation:

• Frequency - Max: The substitute may operate at a lower maximum frequency (133MHz) while remaining compatible with applications designed for the 140MHz specification, provided the actual operating frequency does not exceed the substitute's rating.
• Output Type: LVTTL output is compatible with LVCMOS input requirements in standard clock distribution applications.

The substitute parts 2309-1DCG and 2309-1HDCG, both manufactured by Renesas Electronics Corporation, meet all mandatory parameters and are classified as active products with current availability.

Parameter Comparison

Engineering Selection Recommendations

Both 2309-1DCG and 2309-1HDCG are qualified substitutes for the obsolete SL2309SC-1. Selection between these two Renesas alternatives should be based on the following factors:

Product Availability: The 2309-1HDCG maintains higher inventory levels (2332 Pcs) compared to 2309-1DCG (1021 Pcs), providing greater supply security for production requirements.

Regulatory Compliance: Both substitute parts carry ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements. The original SL2309SC-1 does not specify these certifications.

Frequency Derating: Applications operating at frequencies below 133MHz experience no functional limitation. Systems requiring operation above 133MHz but within the original 140MHz specification must be evaluated for timing margin impact.

Packaging and Thermal Characteristics: Both substitutes maintain identical package geometry, MSL rating, and thermal operating range, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can 2309-1DCG and 2309-1HDCG be used interchangeably?

A: Yes. Both parts are functionally equivalent with identical electrical specifications, package geometry, and pin configuration. Selection between them is determined by inventory availability and supply chain requirements.

Q: What is the impact of the 7MHz frequency reduction (140MHz to 133MHz)?

A: The frequency reduction applies only to the maximum rated specification. If your application operates at frequencies below 133MHz, there is no functional impact. Applications requiring operation above 133MHz must verify timing margins against the lower maximum frequency rating.

Q: Are the LVTTL outputs of the Renesas substitutes compatible with LVCMOS input requirements?

A: LVTTL output levels are compatible with LVCMOS input thresholds in standard clock distribution applications. Both logic families operate within the 3V to 3.6V supply range and share compatible voltage levels for this application category.

Q: Do the substitute parts require any PCB layout changes?

A: No. Both 2309-1DCG and 2309-1HDCG use the identical 16-SOIC package with 0.154" width and 3.90mm body dimension. Direct footprint compatibility is maintained without layout modifications.

Q: What certifications do the substitute parts carry?

A: Both Renesas alternatives are ROHS3 compliant and REACH unaffected, meeting current environmental regulations. The original Skyworks part does not specify these certifications.

Q: Is there a preferred substitute between 2309-1DCG and 2309-1HDCG?

A: Selection is based on supply availability. The 2309-1HDCG currently maintains higher inventory (2332 Pcs vs. 1021 Pcs). Both parts are electrically and mechanically identical.
