TRF3750IPWR Equivalent & Substitute Parts

Part Overview

The TRF3750IPWR is a PLL Frequency Synthesizer IC manufactured by Texas Instruments, designed for 2.4GHz clock/timing applications in a 16-TSSOP surface mount package. The device operates across a 3V to 5.5V supply range with a 2:1 input-to-output ratio and supports differential input/output configurations.

This part is classified as Obsolete, making substitute components necessary for new designs and ongoing production requirements. Alternative parts must maintain functional equivalence within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TRF3750IPWR are grouped based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Package compatibility: 16-TSSOP form factor for direct PCB layout compatibility
• Supply voltage range: Minimum 3V support for operation in existing designs
• Operating temperature range: -40°C to 85°C industrial specification
• Surface mount technology: Consistent with original assembly processes
• RoHS3 compliance: Environmental and regulatory alignment

Secondary Functional Parameters:

• Frequency synthesis capability within or exceeding 2.4GHz specification
• Clock input and output signal support
• Single circuit configuration

The ADF4113BRUZ, ADF4113BRUZ-REEL, and ADF4113BRUZ-REEL7 variants share identical electrical specifications and the same 16-TSSOP package, differing only in packaging format (Tube, standard Reel, or Cut Tape & Digi-Reel). The TRF3765IRHBR represents a higher-performance alternative with extended frequency capability but requires package footprint verification due to 32-VFQFN form factor differences.

Parameter Comparison

Engineering Selection Recommendations

Direct Package-Compatible Substitutes (Recommended for Drop-In Replacement):

The ADF4113BRUZ, ADF4113BRUZ-REEL, and ADF4113BRUZ-REEL7 are functionally equivalent substitutes with identical 16-TSSOP packaging. These Analog Devices parts maintain the same pinout, operating temperature range (-40°C to 85°C), and support the required 2:1 input-to-output ratio. All three variants are Active products with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Selection among these three depends on packaging format requirements: Tube for small quantities, standard Reel for production volumes, or Cut Tape & Digi-Reel for mixed procurement strategies.

Higher-Performance Alternative (Design Modification Required):

The TRF3765IRHBR offers extended frequency capability (4.8GHz) and integrated VCO functionality with a 1:4 input-to-output ratio. This part requires PCB layout modification due to its 32-VFQFN Exposed Pad package format. The supply voltage range is narrower (3V to 3.6V) compared to the original 3V to 5.5V specification. This substitute is suitable for applications requiring higher frequency synthesis or where design revision is feasible.

Compliance and Availability:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original TRF3750IPWR. Current inventory levels support production requirements across all recommended alternatives.

Frequently Asked Questions (FAQ)

Q: Can the ADF4113BRUZ variants be used as direct replacements for the TRF3750IPWR?

A: Yes, the ADF4113BRUZ, ADF4113BRUZ-REEL, and ADF4113BRUZ-REEL7 are direct package-compatible substitutes. They share the identical 16-TSSOP package footprint, support the same 2:1 input-to-output ratio, and operate across the required -40°C to 85°C temperature range. No PCB layout modifications are required.

Q: What is the difference between ADF4113BRUZ, ADF4113BRUZ-REEL, and ADF4113BRUZ-REEL7?

A: These three part numbers represent the same device in different packaging formats. ADF4113BRUZ is supplied in Tube packaging, ADF4113BRUZ-REEL in standard Reel format, and ADF4113BRUZ-REEL7 in Cut Tape & Digi-Reel format. Electrical specifications and pinout are identical across all three variants.

Q: Why does the TRF3765IRHBR have a different package than the original TRF3750IPWR?

A: The TRF3765IRHBR uses a 32-VFQFN Exposed Pad package compared to the 16-TSSOP of the original part. This larger package accommodates additional integrated functionality (Integer-N/Fractional-N VCO) and higher frequency capability (4.8GHz). PCB layout redesign is necessary for this substitute.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all recommended substitute parts (ADF4113BRUZ variants and TRF3765IRHBR) are ROHS3 compliant, matching the environmental compliance of the original TRF3750IPWR.

Q: What is the moisture sensitivity level (MSL) for the substitute parts?

A: The ADF4113BRUZ variants have MSL 1 (Unlimited), identical to the original part. The TRF3765IRHBR has MSL 2 (1 Year), requiring controlled storage conditions during the one-year period from manufacturing.

Q: Can the TRF3765IRHBR be used in applications requiring 5.5V supply voltage?

A: No. The TRF3765IRHBR operates within a 3V to 3.6V supply range, which is narrower than the original TRF3750IPWR specification of 3V to 5.5V. This substitute is not suitable for designs requiring 5V or higher supply voltages.
