Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the obsolete status and RoHS non-compliance before procurement planning. Confirm that the 8-SOIC package dimensions match the design constraints. Check for available alternative components from the manufacturer's current portfolio due to discontinuation. Ensure compatibility with existing 3.135V to 5.5V power rails. Review technical documentation for any specific handling requirements associated with legacy PLL devices.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component only when a fixed 74.18MHz output is strictly required for HDTV compliance. Consider the limited pin count and single-circuit topology against system complexity. Evaluate the impact of RoHS non-compliance on regulatory standards for the target market. Assess whether the external oscillator requirement aligns with board space and bill-of-materials constraints compared to integrated crystal solutions.
