Key Parameters

Substitute Part Grouping Explanation

Parametric equivalence for the Si547 LVDS oscillator is determined by strict alignment across the following critical parameters:

• Output Type and Configuration: LVDS output with Enable/Disable function
• Frequency Support: All four output frequencies (156.25MHz, 176.5625MHz, 307.2MHz, 322.265625MHz) must be supported
• Supply Voltage Range: Multi-voltage operation across 1.8V, 2.5V, and 3.3V
• Frequency Stability: ±20ppm tolerance
• Operating Temperature: -40°C to 85°C range
• Package Specification: 8-SMD, No Lead form factor with identical dimensions (5.00mm x 3.20mm x 1.33mm)
• Current Specifications: Maximum supply current of 121mA and disable current of 112mA
• Compliance: ROHS3 compliance and MSL Level 1 rating

The substitute part 547BAC002434BBG meets all parametric requirements for direct substitution while offering improved product status (Active vs. Not For New Designs).
