MPC9992FA

Overview

The MPC9992FA is a 3.3 V differential ECL/PECL PLL clock generator utilizing SiGe technology and a fully differential design to ensure optimum skew and jitter performance. It features seven differential outputs with frequencies up to 400 MHz and output skews less than 100 ps. The device supports selectable crystal oscillator interfaces or PECL compatible clock inputs, with all control signals being LVCMOS compatible. It operates within an ambient temperature range of 0 °C to +70°C and is housed in a standard 32-lead LQFP package.

Feature Summary

• SiGe technology ensures minimum output skew (max. 100 ps) and optimal PLL jitter performance.
• Supports up to two generated output clock frequencies with a maximum frequency of 400 MHz.
• Features SYNC pulse generation for system synchronization across non-binary frequency relationships.
• Pin and function compatible with the MPC992.

Applications

• Workstation clock distribution
• Mainframe computer systems
• Telecommunication equipment

Procurement Notes

Verify component authenticity through authorized NXP/Freescale distributors. Confirm the FA suffix indicates the standard 32-lead LQFP package. Check for RoHS compliance status as the datasheet notes a Pb-free variant exists under the AC suffix. Ensure supply chain stability due to potential end-of-life status associated with legacy Freescale products.

Selection Notes

Select this component when low skew and high-frequency clock generation are required for workstation or telecom applications. Ensure the application environment stays within the 0 °C to +70°C operating range. Verify that the power supply filtering meets the recommended RC filter specifications for the VCC_PLL pin to maintain jitter performance.

Part Context

The MPC9992FA belongs to the advanced clock driver family from Freescale Semiconductor, now part of NXP. It serves as a direct replacement for the older MPC992 model, offering enhanced performance through SiGe technology while maintaining pin compatibility. This allows for easier upgrades in existing designs requiring higher frequency support and improved jitter characteristics.

Replacement Considerations

The MPC9992FA is pin and function compatible with the MPC992. For lead-free requirements, consider the MPC9992AC variant, which shares the same package and functionality but utilizes a Pb-free construction.
