MPC9230FA

Overview

The MPC9230FA is an 800 MHz Low Voltage PECL Clock Synthesizer manufactured by NXP USA Inc. (formerly Freescale Semiconductor). It operates on a 3.3 V supply and utilizes SiGe technology to generate synthesized clock signals ranging from 50 MHz to 800 MHz. The device features a fully integrated PLL with a VCO frequency range of 800–1600 MHz, differential LVPECL outputs, and an internal crystal oscillator. Configuration is supported via parallel inputs or a serial 3-wire interface. It is housed in a 32-lead LQFP package (Case 873A-04) and supports an ambient temperature range of -40°C to +85°C.

Feature Summary

• Differential LVPECL output capable of frequencies up to 800 MHz
• Integrated PLL with VCO range of 800–1600 MHz
• On-chip crystal oscillator supporting 10–20 MHz reference
• Serial 3-wire and parallel programming interfaces for M and N dividers

Applications

• High-performance telecom equipment clock generation
• Networking infrastructure synchronization
• Computing system clock distribution

Procurement Notes

Verify the specific suffix 'FA' corresponds to the 32-lead LQFP package (Case 873A-04) as defined in the datasheet. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C limits. Ensure power supply filtering is implemented for the VCC_PLL pin to maintain jitter specifications, as the analog section is sensitive to noise in the 1 kHz to 1 MHz range.

Selection Notes

Select this component when low-jitter differential PECL clocks are required for mid-to-high performance applications. The output frequency is determined by the formula FOUT = (fXTAL / 8) * (M / N). Ensure the chosen external crystal matches the series resonance requirement and shunt capacitance specifications (5–7 pF) to guarantee stable oscillation within the VCO range.

Part Context

The MPC9230 belongs to the Advanced Clock Drivers Devices family. It is functionally and pin-compatible with the MC12430. The 'FA' suffix specifically denotes the 32-lead LQFP package variant, distinct from the 28-lead PLCC options available for other suffixes like 'FN' or 'EI'.

Replacement Considerations

The datasheet explicitly states the device is pin and function compatible with the MC12430. No other direct replacement part numbers are documented in the provided source material.
