Renesas MPC9600AE

Overview

MPC9600AE from Integrated Device Technology is a low-voltage, 2.5 V or 3.3 V LVCMOS PLL-based clock driver and 1:21 fanout buffer with fully integrated PLL, 21 LVCMOS outputs (7 per bank), and output frequencies up to 200 MHz. It supports input frequency multiplication by factors of 2, 3, 4, or 6 and delivers ≤150 ps max output-to-output skew - critical for high-speed synchronous systems such as telecom baseband processing and FPGA clock trees.

For engineers reviewing the MPC9600AE datasheet, MPC9600AE pinout, MPC9600AE application, or MPC9600AE equivalent, key selection criteria include its selectable 50–200 MHz output range, LVCMOS/LVPECL reference clock compatibility, 48-lead LQFP package, and zero-delay configuration capability via external feedback.

Technical Context

The MPC9600AE implements a fully integrated analog PLL with no external loop filter required, operating with VCO frequencies from 200 MHz to 400 MHz. Its three independent output banks (QA0–QA6, QB0–QB6, QC0–QC6) each support programmable division-by-2 or division-by-4, enabling flexible multi-frequency clock distribution.

It accepts either single-ended LVCMOS (CCLK) or differential LVPECL (PCLK/PCLK) reference inputs, with REF_SEL selecting between them. The QFB output provides configurable feedback division (÷8 or ÷12), directly determining PLL multiplication factor when connected to FB_IN - enabling precise input-to-output frequency synthesis across four discrete ratios.

Key Specifications

Pinout & Package

The MPC9600AE is housed in a 48-lead LQFP package (Case 932-03), measuring 7 mm × 7 mm × 1.4 mm, with 0.5 mm lead pitch and Pb-free finish. Pin assignment follows standard top-view orientation with corner marker at Pin 1.

FAQ

What is the maximum output frequency supported by the MPC9600AE?

The MPC9600AE supports a maximum output frequency of 200 MHz when configured with ÷2 output dividers (FSELA/FSELB/FSELC = 0) and appropriate input/reference conditions. This is verified across both 2.5 V and 3.3 V supply voltages and over the full industrial temperature range (–40°C to +85°C), as specified in Table 7 of the official datasheet revision 6.

Does the MPC9600AE support both LVCMOS and LVPECL reference inputs?

Yes, the MPC9600AE supports dual-reference input modes: single-ended LVCMOS via the CCLK pin or differential LVPECL via the PCLK/PCLK pair. The REF_SEL pin selects between them - logic low enables CCLK, logic high enables PCLK/PCLK. This flexibility allows integration into mixed-signal clock trees using either CMOS or ECL-level sources.

How does the MPC9600AE achieve zero-delay clock buffering?

The MPC9600AE achieves zero-delay operation by connecting its QFB output to the FB_IN input, closing the PLL feedback loop externally. The internal PLL aligns the rising edge of QFB with the reference input edge, effectively canceling propagation delay. Residual timing uncertainty includes static phase offset (–60 ps to +140 ps), output skew (≤150 ps), and I/O jitter (≤17 ps RMS), as detailed in the Applications Information section.

What is the purpose of the VCCA pin on the MPC9600AE?

The VCCA pin serves two roles: it supplies analog power to the PLL circuitry and functions as a PLL bypass control. When VCCA is driven to GND, the PLL is disabled and the reference clock passes directly to outputs - enabling static functional testing. For normal operation, VCCA requires an external RC filter (e.g., 9–10 Ω resistor + 22 µF capacitor) to suppress noise that would otherwise degrade I/O phase jitter.

Can the MPC9600AE generate different frequencies on each output bank?

Yes, the MPC9600AE can generate up to three distinct frequencies simultaneously - one per bank (QA, QB, QC) - by setting FSELA, FSELB, and FSELC independently to select ÷2 or ÷4 division of the VCO frequency. Combined with FSEL_FB (÷8 or ÷12 feedback), this enables 16 unique input-to-output frequency ratio combinations, as exhaustively listed in Table 8 of the datasheet.
