PRELIMINARY  
XRK39351  
3.3V OR 2.5V, 9-OUTPUT PLL CLOCK DRIVER  
FEBRUARY 2006

input is pulled low. This is a test mode intended for  
system debug purposes.  
GENERAL DESCRIPTION  
The XRK39351 is a low voltage PLL based clock  
driver designed for high speed clock distribution  
applications.  
The XRK39351 has an output/input frequency range  
of 25MHz to 200MHz with the PLL enabled and an  
input frequency range of 2MHz to 300MHz when the  
PLL is disabled (test mode).  
The XRK39351 has two reference clock inputs, one  
LVPECL and the other LVCMOS. The REF_SEL  
input selects clock input to be used as the PLL’s  
reference source.  
FEATURES  
9 LVCMOS Outputs (4 banks)  
25 - 200 MHz output frequency range  
Fully Integrated PLL  
The XRK39351 uses PLL technology to frequency  
lock its outputs to the clock reference input. The  
divider in the feedback path will determine the  
frequency of the VCO. The XRK39351 provides 9  
LVCMOS outputs that are separated into 4 banks.  
Each of the separate output banks can individually  
divide down the VCO output frequency. This allows  
the XRK39351 to generate a variety of output-to-input  
frequency ratios (1:1, 1:2, 1:4, 2:1 and 4:1). All  
outputs provide LVCMOS compatible levels while  
driving 50Ω terminated transmission lines.  
2.5V or 3.3V Operation  
Selectable reference clock input, LVCMOS or  
LVPECL  
150ps max output to output skew  
Pin compatible with MPC9351  
Industrial temp range: -40°C to +85°C  
32-Lead TQFP Packaging  
The input reference clock can be directly applied to  
the output dividers bypassing the PLL when PLL_EN
