SI5317C-C-GM Equivalent & Substitute Parts

Part Overview

The SI5317C-C-GM is an active Jitter Cleaner IC manufactured by Skyworks Solutions Inc., part of the DSPLL® series. This component functions as a clock conditioning device with integrated Phase-Locked Loop (PLL) and bypass capability, designed to reduce timing jitter in clock distribution applications. The device supports multiple input types (Clock, Crystal) and output formats (CML, LVCMOS, LVDS, LVPECL), making it suitable for precision timing applications requiring low-jitter clock signals. With Active product status and ROHS3 compliance, the SI5317C-C-GM remains in full production. Equivalent substitute parts are identified when design requirements permit operation at reduced maximum frequency specifications while maintaining identical electrical interfaces, package geometry, and supply voltage ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SI5317C-C-GM is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Package geometry: 36-VFQFN Exposed Pad (36-QFN 6x6)
• Mounting type: Surface Mount
• Supply voltage range: 1.71V ~ 3.63V
• Input/Output configuration: Clock/Crystal input with CML, LVCMOS, LVDS, LVPECL outputs
• Differential input/output capability: Yes/Yes
• Number of circuits: 1
• Input:Output ratio: 2:2
• PLL with Bypass: Yes
• Operating temperature range: -40°C ~ 85°C
• RoHS compliance: ROHS3 Compliant
• MSL rating: 2 (1 Year)

Variable Parameter Allowing Substitution:

• Maximum frequency specification: The SI5317D-C-GM operates at 100MHz maximum frequency versus the SI5317C-C-GM at 200MHz maximum frequency. This difference permits substitution only in applications where the required clock frequency does not exceed 100MHz.

The SI5317D-C-GM qualifies as a parametric equivalent when system clock requirements remain within its 100MHz maximum frequency specification.

Parameter Comparison

Engineering Selection Recommendations

Both the SI5317C-C-GM and SI5317D-C-GM maintain Active product status with full ROHS3 compliance and identical MSL ratings, ensuring equivalent long-term availability and environmental compliance. Selection between these parts depends solely on maximum frequency requirements:

SI5317C-C-GM Selection Criteria:

• Applications requiring clock frequencies up to 200MHz
• Systems where maximum frequency headroom is necessary
• Designs with potential future frequency scaling requirements

SI5317D-C-GM Selection Criteria:

• Applications with maximum clock frequency requirements of 100MHz or below
• Cost optimization scenarios where reduced frequency specification is acceptable
• Designs where frequency ceiling does not exceed 100MHz specification

Both devices share identical package geometry (36-QFN 6x6), supply voltage range (1.71V ~ 3.63V), operating temperature range (-40°C ~ 85°C), and functional architecture (PLL with bypass, dual input/output configuration). PCB layout and schematic integration remain unchanged between parts. No design modifications are required when substituting between these devices, provided the application frequency requirement does not exceed the substitute part's maximum specification.

Frequently Asked Questions (FAQ)

Q: Can SI5317D-C-GM replace SI5317C-C-GM in all applications?

A: SI5317D-C-GM can replace SI5317C-C-GM only when the system's maximum required clock frequency does not exceed 100MHz.
