MPC9850VM

Overview

The MPC9850VM is a PLL-based clock generator designed for PowerQUICC III microprocessor applications. It features one circuit with LVCMOS, LVPECL, and crystal inputs, producing LVCMOS and LVDS outputs up to 500 MHz. The device operates on a 3.135V to 3.465V supply within a -40°C to +85°C range. Packaged in a 100-lead MAPBGA (11x11mm), it generates processor clocks and Rapid I/O signals using a 2 GHz VCO, supporting frequencies from 15.87 MHz to 200 MHz for banks A/B and 50/125/250/500 MHz for bank C.

Feature Summary

• Generates 8 low-skew LVCMOS outputs across two banks (A and B) for processor and system components
• Provides 2 differential LVDS outputs (Bank C) specifically for Rapid I/O interfaces at 125, 250, or 500 MHz
• Supports 25 MHz or 33 MHz reference inputs via external clock or internal oscillator with a 25 MHz crystal
• Configurable output frequencies selectable via hardware pins, including standard bus speeds like 100, 133, and 166 MHz

Applications

• PowerQUICC III Microprocessor and Microcontroller systems
• Telecommunications networking equipment
• Computing platforms requiring high-speed Rapid I/O interfaces

Procurement Notes

Verify the VM suffix indicates a lead-free package variant of the standard MPC9850. Confirm availability as this component may be subject to end-of-life status given its 2005 datasheet revision and subsequent acquisition history. Ensure the 100-lead MAPBGA footprint matches the target PCB design constraints.

Selection Notes

Select this device when designing for PowerQUICC III architectures requiring specific Rapid I/O clock rates. Ensure the input reference frequency matches the available 25 MHz or 33 MHz sources. Verify that the 3.3V core voltage and compatible LVCMOS/LVDS output drive levels align with the downstream logic requirements.

Part Context

The MPC9850 was originally developed by Freescale Semiconductor for PowerQUICC III processors. The timing solutions organization was later acquired by Integrated Device Technology (IDT). The product line is now managed under Renesas Electronics Corporation following IDT's acquisition. This part represents a specialized clock generator for legacy high-performance communication processors.
