MPC9865VMR2

Overview

The MPC9865VMR2 is a PLL-based clock generator designed for PowerQUICC III microprocessor applications. It generates eight low-skew LVCMOS outputs across two configurable banks, supporting frequencies from 16 MHz to 200 MHz derived from a 2 GHz internal VCO. The device accepts 25 MHz or 33 MHz reference inputs via crystal or external sources (LVCMOS/LVPECL). Operating on a 3.3 V supply with an extended temperature range of -40°C to +85°C, it utilizes a 100-lead CABGA package.

Feature Summary

• Generates up to eight LVCMOS clock outputs in two independent banks with selectable frequencies between 16 MHz and 200 MHz.
• Supports multiple input references including 25 MHz/33 MHz crystals, single-ended LVCMOS, and differential LVPECL signals.
• Features low cycle-to-cycle and period jitter specifications suitable for high-performance processor timing.
• Includes buffered reference clock outputs for downstream components such as Ethernet PHYs.

Applications

• PowerQUICC III Microprocessor Clock Generation
• Telecommunications Networking Equipment
• High-Speed Computing Systems

Procurement Notes

Verify component status as the MPC9865 series has reached End-of-Life (EOL) per manufacturer notices dated February 2016. Confirm availability through authorized distributors or secondary markets. Ensure the VM suffix indicates Pb-free packaging compatible with current assembly processes. Validate pinout compatibility during replacement planning.

Selection Notes

Select this component when designing systems requiring specific PowerPC/PowerQUICC bus frequencies. Ensure the design accommodates the 3.3 V core supply and optional 2.5 V or 3.3 V output supplies. Verify that the required output frequencies align with the available division ratios (N=8 to 126). Consider the 100-lead MAPBGA footprint constraints during PCB layout.

Part Context

Originally manufactured by Freescale Semiconductor, the MPC9865 was acquired by Integrated Device Technology (IDT) and subsequently by Renesas Electronics Corporation. The part number suffix 'VM' denotes the lead-free variant housed in a 100-lead MAPBGA package. This device belongs to the NETCOM family of advanced clock drivers optimized for networking and telecom infrastructure.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Due to the EOL status, engineers should evaluate newer Renesas VersaClock or FemtoClock families for functional equivalents, ensuring voltage levels and package dimensions match the existing design.

FAQ

What is the maximum output frequency supported by the MPC9865?

The maximum output frequency is 200 MHz, achieved by dividing the 2000 MHz VCO frequency by a factor of 10.

Can the MPC9865 accept differential clock inputs?

Yes, the device supports differential LVPECL inputs on pins PCLK and PCLK, in addition to single-ended LVCMOS and crystal inputs.

How are the output frequencies configured?

Output frequencies are configured using digital control pins CLK_A and CLK_B, which set the division ratio N for Bank A and Bank B respectively.
