Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Renesas 87322BYILF is determined by the following critical parameters:

• Package / Case: 52-LQFP (10x10) surface mount footprint
• Input-to-Output Ratio: 2:15
• Differential Input and Output capability: Yes/Yes
• Output Type: LVPECL
• Operating Temperature Range: -40°C ~ 85°C
• Voltage Supply Range: Compatible with 3V ~ 3.8V operation
• Number of Circuits: Single circuit configuration

The Microchip SY100E222LTY meets all substitution criteria. While it operates at a higher maximum frequency (1.5GHz versus 750MHz), this represents an enhancement rather than a limitation, as the device maintains backward compatibility with the input-to-output ratio, differential signaling requirements, and package specifications of the original part.

Parameter Comparison

Engineering Selection Recommendations

The Microchip SY100E222LTY is the qualified substitute for the Renesas 87322BYILF based on the following factors:

Functional Equivalence: Both devices maintain identical input-to-output ratios (2:15), differential signaling architecture, and LVPECL output specifications. The SY100E222LTY's higher maximum frequency (1.5GHz) does not create incompatibility; it represents enhanced performance headroom.

Package and Thermal Compatibility: Both parts use the 52-LQFP surface mount package with identical footprints and thermal characteristics. Operating temperature ranges are identical (-40°C ~ 85°C), ensuring thermal performance parity.

Supply Voltage: The SY100E222LTY operates within a 3V ~ 3.6V range, which is a subset of the original part's 3V ~ 3.8V specification. This ensures compatibility in systems designed for the Renesas device.

Compliance and Availability: The SY100E222LTY holds active product status with ROHS3 compliance, addressing the obsolescence of the original Renesas part and meeting current regulatory requirements. Inventory availability (1341 pieces) supports production continuity.

Moisture Sensitivity: Both devices share identical MSL ratings (3, 168 Hours), requiring equivalent handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the Microchip SY100E222LTY directly replace the Renesas 87322BYILF without PCB modifications?

A: Yes. Both devices use the 52-LQFP package with identical pin assignments and functional specifications. No PCB layout changes are required for substitution.

Q: Why does the SY100E222LTY operate at 1.5GHz when the original part is rated for 750MHz?

A: The higher frequency rating indicates enhanced performance capability. The device remains fully compatible with systems designed for 750MHz operation, as it can operate at lower frequencies without functional degradation.

Q: Are the input signal types compatible between the two devices?

A: The SY100E222LTY accepts LVECL and LVPECL inputs, while the Renesas part accepts CML, LVDS, LVPECL, and SSTL inputs. For substitution, ensure your system uses LVPECL input signals, which both devices support.

Q: What are the supply voltage considerations for substitution?

A: The SY100E222LTY operates within 3V ~ 3.6V. If your system requires operation above 3.6V, verify that the Renesas part's extended range (up to 3.8V) is necessary. Most applications operate within the 3V ~ 3.6V window, making the substitute fully compatible.

Q: Does the SY100E222LTY require different handling procedures due to its ROHS3 compliance?

A: No. Both devices share identical Moisture Sensitivity Level ratings (MSL 3, 168 Hours). Standard handling and storage protocols for MSL 3 components apply to both parts.

Q: Can I use the SY100E222LTY in legacy systems originally designed for the Renesas 87322BYILF?

A: Yes. The identical package, pin configuration, input-to-output ratio, and differential signaling architecture ensure functional compatibility in existing designs. The active product status of the SY100E222LTY provides long-term supply security for legacy system support.
