Substitute Part Grouping Explanation

Substitute parts for the 23S08-1DCGI are identified based on the following critical parameters that determine functional compatibility:

Mechanical Compatibility:

Package / Case: 16-SOIC (0.154", 3.90mm Width)
Mounting Type: Surface Mount

Electrical Compatibility:

Voltage - Supply: 3V ~ 3.6V
Operating Temperature: -40°C ~ 85°C
Input Type: LVTTL
Output Type: LVTTL (common to both main and substitute parts)
PLL: Yes with Bypass
Number of Circuits: 1

Performance Parameters:

Maximum Frequency capability must meet or exceed application requirements
Input-to-Output Ratio must support the required clock multiplication

The substitute parts CDCVF25081D and CDCVF25081DR, both manufactured by Texas Instruments, meet these compatibility criteria. Both devices share identical electrical specifications and package form factors with the 23S08-1DCGI, enabling direct substitution in applications requiring clock multiplication and zero delay buffering functionality.

Engineering Selection Recommendations

The 23S08-1DCGI is classified as obsolete, necessitating the use of active substitute parts for new procurement and long-term system support. Both CDCVF25081D and CDCVF25081DR are active products manufactured by Texas Instruments and provide direct functional equivalence.

CDCVF25081D is supplied in Tube packaging and is suitable for applications requiring standard component quantities.

CDCVF25081DR is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, optimized for high-volume production environments and automated assembly processes.

Both substitute parts exceed the performance specifications of the original 23S08-1DCGI, operating at 200MHz maximum frequency compared to 133.3MHz, and feature improved moisture sensitivity ratings (MSL 1 versus MSL 3). All three devices maintain ROHS3 compliance and identical supply voltage and operating temperature ranges, ensuring seamless integration into existing designs.

Frequently Asked Questions (FAQ)

Q: Can CDCVF25081D and CDCVF25081DR be used interchangeably with the 23S08-1DCGI?

A: Yes. Both Texas Instruments devices share identical electrical specifications, package form factors, and pin configurations with the 23S08-1DCGI. The primary difference between CDCVF25081D and CDCVF25081DR is packaging format: Tube versus Cut Tape and Digi-Reel®. Selection depends on procurement and assembly requirements.

Q: What is the difference between CDCVF25081D and CDCVF25081DR?

A: Both parts are electrically identical. CDCVF25081D is supplied in Tube packaging for standard component handling. CDCVF25081DR is supplied in Cut Tape (CT) and Digi-Reel® packaging, designed for automated pick-and-place assembly and high-volume production workflows.

Q: Are there any performance differences between the 23S08-1DCGI and the substitute parts?

A: The substitute parts operate at higher maximum frequencies (200MHz versus 133.3MHz) and feature superior moisture sensitivity ratings (MSL 1 versus MSL 3). These represent performance improvements over the original part. The input-to-output ratio differs (2:8 versus 1:8), which must be evaluated against specific application requirements.

Q: Do the substitute parts maintain the same supply voltage and operating temperature range?

A: Yes. All three devices operate within 3V to 3.6V supply voltage and -40°C to 85°C operating temperature ranges, ensuring compatibility with existing power distribution and thermal management designs.

Q: Are ROHS3 compliance and REACH status maintained with the substitute parts?

A: Yes. Both CDCVF25081D and CDCVF25081DR are ROHS3 compliant and REACH unaffected, matching the compliance profile of the 23S08-1DCGI.
