MPC9230EI

Overview

The MPC9230EI is a low voltage PECL clock synthesizer manufactured by Integrated Device Technology, now part of Renesas Electronics. It operates on a single 3.3 V supply and generates differential LVPECL output signals ranging from 50 MHz to 800 MHz. The device features an internal PLL with a VCO frequency range of 800 MHz to 1600 MHz (limited to 1500 MHz at -40°C to +85°C). It supports both serial and parallel programming interfaces for configuring the M and N dividers. The EI suffix indicates a lead-free 28-lead PLCC package compliant with RoHS standards.

Feature Summary

• Differential LVPECL outputs capable of frequencies up to 800 MHz
• Integrated PLL with VCO operating between 800 MHz and 1600 MHz
• Dual configuration via serial 3-wire or parallel interface
• On-chip crystal oscillator supporting external quartz crystals

Applications

• Telecommunications equipment clock generation
• High-performance networking infrastructure
• Computing system timing solutions

Procurement Notes

Verify that the component bears the 'EI' suffix to confirm it is the lead-free version housed in a 28-lead PLCC package. Ensure the source documentation corresponds to IDT or Renesas official specifications, as the manufacturer was acquired. Confirm the revision level matches the provided datasheet.

Selection Notes

Select this component when a 3.3 V supply and differential LVPECL outputs are required. The maximum output frequency is limited to 750 MHz in the extended temperature range (-40°C to +85°C), while reaching 800 MHz only within the commercial range (0°C to +70°C). Ensure the application can accommodate the specific power supply filtering requirements for the VCC_PLL pin to minimize jitter.

Part Context

This device belongs to the MPC9230 family of clock synthesizers. The 'EI' designation specifically identifies the lead-free variant packaged in a 28-lead Plastic Leadless Chip Carrier (PLCC). Other variants include the FN suffix for standard PLCC and FA/AQ suffixes for LQFP packages. The device is functionally compatible with the MC12430.

Replacement Considerations

The MPC9230 is pin and function compatible with the MC12430. Substitution should be verified against the specific electrical characteristics and package dimensions of the target replacement.
