1. 514FBB000115CAGR Substitution Conclusion
From a key parameter perspective, the 514FBB000115CAGR is fully compatible with the original part in terms of package footprint, supply voltage (2.5V), output type (LVDS), and enable function, allowing for a direct drop-in replacement. The primary differences lie in its superior frequency stability (±25ppm vs ±30ppm) and significantly lower operating current (max 23mA vs 65mA, disable current 18mA vs 22mA). Substitution results in a slight improvement in system timing accuracy alongside a substantial reduction in power consumption, which benefits thermal design and power supply loading. However, it is important to note that the low-power design may correspond to different output drive strength or internal circuitry. Signal integrity should be validated under conditions of extremely high load or long transmission lines to ensure requirements are met.
2. 510FBA125M000CAGR Substitution Conclusion
The 510FBA125M000CAGR matches the original part in package, voltage, output, and functional interfaces, providing the physical basis for a direct replacement. Its technical specifications are nearly identical to those of the 514FBB000115CAGR, including the improved frequency stability (±25ppm) and lower operating current (max 23mA). The main distinction is implied in the part number description (noted as "DIFFERENTIAL/SINGLE-ENDED; SINGL"), which likely indicates it is configured for pure differential output without a single-ended switching option—a detail not explicitly defined for the original part. If the original system relies on I2C or programmable features, this substitute may not be suitable. However, as a fixed-frequency LVDS clock source, its advantages in power efficiency and precision are clear, making it well-suited for power-sensitive applications that do not require output mode reconfiguration.
