SI4113-D-GT Equivalent & Substitute Parts

Part Overview

The SI4113-D-GT is a Frequency Synthesizer IC manufactured by Skyworks Solutions Inc., designed for clock and timing applications. This active product operates at a maximum frequency of 1.8GHz with a 1:2 input-to-output ratio and is housed in a 24-TSSOP surface mount package. The device accepts crystal input and provides clock output through an integrated Phase-Locked Loop (PLL) circuit.

Substitute parts are identified when design requirements permit operation at alternative frequency specifications or when inventory constraints necessitate component alternatives while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the SI4113-D-GT are qualified based on the following criteria:

Mechanical Compatibility: All substitute parts must use the identical 24-TSSOP (0.173", 4.40mm Width) surface mount package to ensure PCB layout and assembly process compatibility.

Electrical Core Specifications: All substitute parts must maintain the same supply voltage range (2.7V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and functional architecture (Frequency Synthesizer with PLL, crystal input, clock output).

Frequency and Ratio Parameters: Substitutes are grouped by maximum frequency specification and input-to-output ratio. The SI4113-D-GT operates at 1.8GHz with a 1:2 ratio. Alternative frequency specifications are permitted when system design allows operation at lower maximum frequencies.

Manufacturer Consistency: All substitute parts are manufactured by Skyworks Solutions Inc., ensuring consistent design philosophy and reliability standards.

Parameter Comparison

Engineering Selection Recommendations

SI4113-D-GT (Primary Part): Select this part for applications requiring 1.8GHz maximum frequency operation with 1:2 input-to-output ratio. Active product status ensures ongoing manufacturer support and supply availability.

SI4112-D-GT (Lower Frequency Alternative): This substitute operates at a maximum frequency of 1GHz with a 1:1 input-to-output ratio. Selection is appropriate only when system design specifications permit operation at reduced frequency and the 1:1 ratio meets functional requirements. This part demonstrates RoHS3 compliance and REACH unaffected status. Higher inventory availability (2044 Pcs) may support extended production runs.

SI4123-D-GT (Frequency and Ratio Match): This substitute matches the SI4113-D-GT in both maximum frequency (1.8GHz) and input-to-output ratio (1:2), providing direct functional equivalence. Selection is appropriate when SI4113-D-GT availability is constrained. Active product status and identical electrical specifications ensure seamless integration.

All three parts share identical supply voltage range, operating temperature range, package specification, and MSL rating, confirming mechanical and thermal compatibility across the substitute group.

Frequently Asked Questions (FAQ)

Q: Can SI4112-D-GT replace SI4113-D-GT in all applications?

A: No. SI4112-D-GT operates at a maximum frequency of 1GHz with a 1:1 input-to-output ratio, compared to SI4113-D-GT's 1.8GHz and 1:2 ratio. Substitution is vali
