CDCLVC1102PWR Equivalent & Substitute Parts

Part Overview

The CDCLVC1102PWR is a clock fanout buffer (distribution) IC manufactured by Texas Instruments, designed for 1:2 clock distribution at frequencies up to 250 MHz. This single-circuit LVCMOS buffer operates across a 2.3V to 3.6V supply range and is housed in an 8-TSSOP surface mount package. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameters of the clock distribution IC category, particularly when the original part faces supply constraints or when alternative packaging formats are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the CDCLVC1102PWR is based on the following allowed parameters for clock fanout buffer ICs:

Primary Substitution Criteria:

• Fanout buffer (distribution) type with 1:2 input-to-output ratio
• Surface mount 8-TSSOP package format
• Operating temperature range of -40°C to 85°C
• ROHS3 compliance and active product status
• Compatible input/output signal types

Frequency Consideration: Substitute parts may operate at different maximum frequencies (200 MHz to 2.5 GHz) provided the application does not exceed the substitute part's frequency specification. Lower frequency parts (200 MHz) are suitable for applications requiring ≤200 MHz operation. Higher frequency parts (2.5 GHz) provide extended frequency capability.

Voltage Supply Range: Substitute parts must support overlapping or compatible supply voltage ranges. The CDCLVC1102PWR operates at 2.3V to 3.6V; substitutes with ranges including 3.3V operation are compatible for standard logic applications.

Signal Type Compatibility: The CDCLVC1102PWR uses LVCMOS input and output. Substitutes with LVCMOS capability are direct functional equivalents. Parts with differential input/output types (CML, LVDS, LVPECL, ECL) represent functional alternatives for applications requiring differential signaling.

Packaging Format: All identified substitutes maintain the 8-TSSOP surface mount package, ensuring mechanical and thermal compatibility with the original design.

Parameter Comparison

Engineering Selection Recommendations

5PB1102PGGI (Renesas Electronics): This substitute is suitable for applications operating at frequencies up to 200 MHz. It maintains LVCMOS input and output compatibility with the CDCLVC1102PWR and operates across a supply range of 1.71V to 3.465V, which overlaps the original part's 2.3V to 3.6V specification at standard 3.3V logic levels. Both parts share identical operating temperature range (-40°C to 85°C), ROHS3 compliance, and MSL 1 rating. Selection of this part is appropriate when frequency requirements do not exceed 200 MHz and when Renesas component qualification is acceptable.

853S011BGILF (Renesas Electronics): This substitute provides extended frequency capability up to 2.5 GHz and supports differential signaling types (CML, LVDS, LVPECL, SSTL input; ECL, LVPECL output). The part operates across 2.375V to 3.8V supply range and maintains the 8-TSSOP package format. However, this part carries MSL 3 (168 Hours) moisture sensitivity, requiring controlled storage and handling compared to the MSL 1 rating of the original part. Selection is appropriate for high-frequency applications requiring differential signal support, with consideration for moisture sensitivity management during storage and assembly.

853S011BGILFT (Renesas Electronics): This substitute is functionally equivalent to 853S011BGILF, offering the same 2.5 GHz frequency capability and differential signaling support (CML, LVDS, LVPECL, SSTL input; ECL, LVPECL output). The key distinction is the MSL 1 (Unlimited) moisture sensitivity rating, matching the original CDCLVC1102PWR specification. Supply voltage range is 2.375V to 3.8V. This part is supplied in Cut Tape (CT) & Digi-Reel® format, consistent with the original part's packaging. Selection is appropriate for high-frequency applications requiring differential signaling without additional moisture sensitivity constraints.

All substitute parts maintain active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can the 5PB1102PGGI replace the CDCLVC1102PWR in all applications?

A: The 5PB1102PGGI is a suitable substitute for applications operating at frequencies up to 200 MHz. If your application requires clock distribution at frequencies between 200 MHz and 250 MHz, the 5PB1102PGGI will not meet the frequency specification. Both parts share LVCMOS input/output compatibility, identical operating temperature range, and MSL 1 moisture sensitivity rating.

Q: What is the difference between the 853S011BGILF and 853S011BGILFT?

A: Both parts are functionally identical in terms of frequency capability (2.5 GHz), signal types (differential CML, LVDS, LVPECL, SSTL input; ECL, LVPECL output), and supply voltage range (2.375V to 3.8V). The primary difference is moisture sensitivity: 853S011BGILF carries MSL 3 (168 Hours), while 853S011BGILFT carries MSL 1 (Unlimited). Additionally, 853S011BGILFT is supplied in Cut Tape (CT) & Digi-Reel® format, matching the original part's packaging, whereas 853S011BGILF is supplied in Tube format.

Q: Are the 853S011 parts direct replacements for LVCMOS applications?

A: The 853S011 parts (both BGILF and BGILFT) support differential signaling types including LVPECL output, which differs from the CDCLVC1102PWR's LVCMOS output. While these parts can operate in LVCMOS-compatible environments at 3.3V supply, they are designed for differential clock distribution applications. Use these parts when your application requires differential signal support or extended frequency operation beyond 250 MHz.

Q: Does package size differ between these substitutes?

A: The CDCLVC1102PWR and 5PB1102PGGI both use 8-TSSOP package with 0.173" width (4.40mm). The 853S011BGILF and 853S011BGILFT use 8-TSSOP or 8-MSOP package with 0.118" width (3.00mm). While both are 8-pin TSSOP packages, the physical dimensions differ. Verify PCB layout compatibility before substitution.

Q: What are the supply voltage compatibility considerations?

A: The CDCLVC1102PWR operates at 2.3V to 3.6V. The 5PB1102PGGI operates at 1.71V to 3.465V, providing broader low-voltage support. The 853S011 parts operate at 2.375V to 3.8V. All three substitutes support standard 3.3V logic operation. For 2.5V or lower supply applications, verify the substitute part's minimum voltage specification.

Q: What does MSL rating mean for component selection?

A: Moisture Sensitivity Level (MSL) indicates how long a component can be exposed to ambient conditions before assembly. MSL 1 (Unlimited) allows indefinite storage without special handling. MSL 3 (168 Hours) requires controlled storage and must be assembled within 168 hours of package opening. The CDCLVC1102PWR and 853S011BGILFT carry MSL 1, while 853S011BGILF carries MSL 3, requiring additional moisture management during manufacturing.
