CLC016MTC/NOPB Equivalent & Substitute Parts

Part Overview

The CLC016MTC/NOPB is a Phase Lock Loop (PLL) IC manufactured by Texas Instruments, housed in a 28-TSSOP package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The CLC016MTC/NOPB provides single-circuit PLL functionality with ECL/PECL input and output capabilities, operating within a 4.5V to 5.5V supply range and supporting a 1:2 input-to-output frequency ratio with differential signal processing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLC016MTC/NOPB is determined by the following critical parameters:

• Signal Interface Compatibility: Input and output signal types (ECL/PECL differential signaling)
• Frequency Ratio: 1:2 input-to-output multiplication capability
• Supply Voltage Range: Operation within 4.5V to 5.5V envelope
• Package Compatibility: Surface mount form factor with compatible pin pitch and thermal characteristics
• Differential Signal Processing: Requirement for differential input and output handling
• Product Availability: Active or in-stock status for procurement

The identified substitute part, LMH0026MH/NOPB, operates in a related clock/timing domain with surface mount packaging. However, this part functions as a video reclocker for DVB-ASI and SMPTE standards, representing a functional category shift from the original PLL application. Substitution feasibility depends on whether the target application can accommodate the reclocker function and the different supply voltage specification (3.135V ~ 3.465V).

Parameter Comparison

Engineering Selection Recommendations

Selection between the CLC016MTC/NOPB and LMH0026MH/NOPB must account for the following factors:

CLC016MTC/NOPB Considerations: This part is obsolete and ROHS3 compliant. Existing inventory of 1,099 pieces is available for immediate procurement. Use this part only for legacy system maintenance or when existing designs are locked to this specific component.

LMH0026MH/NOPB Considerations: This part carries active product status with 1,562 pieces in stock. It is designed for professional video applications using DVB-ASI and SMPTE standards. The supply voltage range (3.135V ~ 3.465V) differs significantly from the original part, requiring circuit redesign if substitution is pursued. The package footprint is compatible (both 0.173" width TSSOP variants), but pin count differs (20 vs. 28 pins).

Direct functional substitution is not recommended without comprehensive application analysis. The LMH0026MH/NOPB serves a different functional purpose (video reclocker vs. general-purpose PLL) and operates at a different supply voltage. Substitution is viable only if the target application can accommodate video reclocker functionality and the lower supply voltage specification.

Frequently Asked Questions (FAQ)

Q: Can the LMH0026MH/NOPB directly replace the CLC016MTC/NOPB in existing designs?

A: Direct replacement is not recommended without design modification. The LMH0026MH/NOPB operates at 3.135V ~ 3.465V supply voltage, compared to the CLC016MTC/NOPB's 4.5V ~ 5.5V range. Additionally, the LMH0026MH/NOPB is a video reclocker for DVB-ASI/SMPTE applications, not a general-purpose PLL. Pin count also differs (20 vs. 28 pins).

Q: What are the key differences in package compatibility?

A: Both parts use TSSOP packages with 0.173" width and 4.40mm body width, making the physical footprint compatible. However, the CLC016MTC/NOPB uses a 28-pin configuration while the LMH0026MH/NOPB uses a 20-pin configuration. PCB layout and schematic redesign is required for substitution.

Q: Why is the CLC016MTC/NOPB classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. Existing inventory remains available for purchase, but no new manufacturing runs are planned. For new designs, active alternatives should be evaluated.

Q: What compliance certifications apply to these parts?

A: The CLC016MTC/NOPB is ROHS3 compliant with MSL rating of 3 (168 hours). RoHS compliance status for the LMH0026MH/NOPB is not specified in the provided data and should be verified with the manufacturer before procurement.

Q: Are there other substitute parts available for the CLC016MTC/NOPB?

A: Based on the provided data, LMH0026MH/NOPB is the identified substitute. Additional alternatives may exist in the market but are not included in this reference.
