Procurement Notes

This component has been officially discontinued and is no longer in production. Availability is limited to existing stock or surplus channels. Verification of the part status as End-of-Life (EOL) is required before procurement planning. Alternative components should be evaluated for system compatibility.

Selection Notes

Designers requiring this specific clock buffer configuration must consider that the 9ZXL1230AKLFT is obsolete. Selection should focus on identifying pin-compatible or functionally equivalent replacements from the manufacturer's current portfolio. Verify that the replacement supports the required 150MHz frequency and 1:12 ratio for the target application.

Part Context

The 9ZXL1230AKLFT belongs to the 9ZXL series of zero-delay clock buffers. It serves as a low-power solution for distributing clock signals in high-speed digital systems. The device integrates PLL functionality to minimize jitter and skew, ensuring precise timing alignment for connected peripherals in server and networking equipment.

Replacement Considerations

The 9ZXL1231EKILFT is listed as a similar replacement option. This alternative offers a 400MHz maximum frequency and operates within a -40°C to 85°C temperature range, providing enhanced performance specifications compared to the discontinued model.
