The MPC9600 is a fully LVCMOS 2.5 V or 3.3 V compatible PLL clock
48鈥揕EAD LQFP PACKAGE
driver. The MPC9600 has the capability to generate clock signals of 50 to
CASE 932鈥?3
200 MHz from clock sources of 16.67 to 50 MHz. The internal PLL is
optimized for this frequency range and does not require external loop filter
components. QFB provides an output for the external feedback path to
the feedback input FB_IN. The QFB divider ratio is configurable and
determines the PLL frequency multiplication factor when QFB is directly
connected to FB_IN. The MPC9600 is optimized for minimizing the
propagation delay between the clock input and FB_IN.
Three output banks of 7 outputs each bank can be individually configured to divide the VCO frequency by 2 or by 4. Combining
the feedback and output divider ratios, the MPC9600 is capable to multiply the input frequency by 2, 3, 4 and 6.
The reference clock is selectable either LVPECL or LVCMOS. The LVPECL reference clock feature allows the designer to use
LVPECL fanout buffers for the inner branches of the clock distribution tree. All control inputs accept LVCMOS compatible levels.
The outputs provide low impedance LVCMOS outputs capable of driving parallel terminated 50
鈩?/div>
transmission to VTT=VCC/2.
For series terminated lines the MPC9600 can drive two lines per output giving the device an effective total fanout of 1:42. With
guaranteed maximum output-to-output skew of 150 ps, the MPC9600 PLL clock driver meets the synchronization requirements
of the most demanding systems.
The VCCA analog power pin doubles as a PLL bypass select line for test purpose. When the VCCA is driven to GND the
reference clock will bypass the PLL.
The device is packaged in a 48-lead LQFP package to provide optimum combination of board density and performance.
