Renesas 8530DYLF Clock Fanout Buffer Equivalent & Substitute Parts

Part Overview

The Renesas 8530DYLF is a Clock Fanout Buffer (Distribution) IC with 1:16 output ratio and 500 MHz maximum frequency. This component is classified as Obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. The 8530DYLF accepts multiple input signal types (HCSL, LVDS, LVHSTL, LVPECL, SSTL) and outputs LVPECL signals in a 48-LQFP surface mount package.

Substitute Part Grouping Explanation

Substitute parts for the 8530DYLF are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Type: Fanout Buffer (Distribution) IC
• Number of Circuits: 1
• Differential Input and Output capability: Yes/Yes
• Input signal compatibility: Must accept at least one of the specified input types (HCSL, LVDS, LVHSTL, LVPECL, SSTL)
• Output signal type: LVPECL
• Frequency capability: Minimum 500 MHz
• Supply voltage overlap: Must operate within or encompass the 2.375V ~ 3.465V range
• Mounting type: Surface Mount
• Package compatibility: 48-pin QFP variants

Substitute Parts Identified:

1. SY898530UTZ (Microchip Technology) - Direct functional equivalent with identical 1:16 ratio and 500 MHz frequency. Active product status. Supply voltage range 3.135V ~ 3.465V (subset of original range). Identical package footprint 48-TQFP (7x7).

2. 8SLVS1118NLGI (Renesas Electronics Corporation) - Manufacturer-recommended alternative with enhanced specifications. Higher output ratio (1:18), increased frequency capability (2 GHz), dual supply voltage support (2.375V ~ 2.625V and 3.135V ~ 3.465V), extended operating temperature range (-40°C ~ 85°C). Package variant: 48-VFQFN Exposed Pad with identical 7x7 footprint dimensions. Active product status.

Parameter Comparison

Engineering Selection Recommendations

SY898530UTZ Selection Criteria:

• Direct pin-compatible replacement for 8530DYLF
• Identical electrical specifications (1:16 ratio, 500 MHz, LVPECL output)
• Active product status ensures long-term availability
• ROHS3 compliant and MSL 3 rated
• Supply voltage range 3.135V ~ 3.465V is a subset of the original specification; applications requiring operation below 3.135V cannot use this substitute
• 48-TQFP package footprint matches original design

8SLVS1118NLGI Selection Criteria:

• Manufacturer-recommended alternative from Renesas Electronics
• Enhanced performance specifications (1:18 ratio, 2 GHz frequency capability)
• Active product status with extended operating temperature range (-40°C ~ 85°C)
• Dual supply voltage support provides broader application flexibility
• ROHS3 compliant and MSL 3 rated
• 48-VFQFN package with exposed pad; identical 7x7 footprint but different pin configuration requires PCB layout evaluation
• Output signal flexibility (LVDS or LVPECL) accommodates various system requirements

Frequently Asked Questions (FAQ)

Q: Can SY898530UTZ be used as a direct replacement for 8530DYLF in all applications?

A: SY898530UTZ provides electrical equivalence for the 1:16 fanout buffer function at 500 MHz with LVPECL output. However, the supply voltage range difference (3.135V ~ 3.465V versus 2.375V ~ 3.465V) means applications requiring operation below 3.135V require design modification or selection of an alternative part.

Q: What are the key differences between SY898530UTZ and 8SLVS1118NLGI?

A: SY898530UTZ is a direct functional equivalent (1:16, 500 MHz) from Microchip Technology. The 8SLVS1118NLGI is a Renesas-recommended alternative with enhanced specifications: higher output ratio (1:18), increased frequency capability (2 GHz), extended temperature range (-40°C ~ 85°C), and dual supply voltage support. The 8SLVS1118NLGI uses a different package variant (48-VFQFN versus 48-TQFP), requiring PCB layout verification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both SY898530UTZ and 8SLVS1118NLGI are ROHS3 compliant with MSL 3 (168 Hours) rating, matching the original 8530DYLF specifications.

Q: What is the impact of package differences between 48-TQFP and 48-VFQFN?

A: Both packages maintain identical 7x7 mm footprint dimensions. The 48-VFQFN variant includes an exposed pad for enhanced thermal performance. Pin configuration differences require PCB layout review to confirm compatibility with existing designs.

Q: Which substitute part should be selected for new designs?

A: Selection depends on application requirements. For direct replacement with minimal design changes, use SY898530UTZ. For new designs requiring enhanced performance, extended temperature range, or higher frequency capability, use 8SLVS1118NLGI.
