Low Voltage, LVCMOS/LVPECL-to-LVPECL/ECL  
Clock Generator  
843N001I  
DATASHEET  
GENERAL DESCRIPTION  
FEATURES  
Fourteen differential 3.3V LVPECL/ECL outputs  
Selectable differential or REF_CLK inputs  
The 873991-147 is a low voltage, low skew, 3.3V LVPECL or ECL  
Clock Generator and a member of the family of High Performance  
Clock Solutions from IDT.The 873991-147 has two selectable clock  
inputs. The CLK, nCLK pair can accept LVPECL, LVDS, LVHSTL,  
SSTL and HCSL input levels and, the REF_CLK pin can accept a  
LVCMOS or LVTTL input levels. This device has a fully integrated  
PLL along with frequency configurable outputs.An external feedback  
input and output regenerates clocks with “zero delay”.  
CLK, nCLK can accept the following input levels:  
LVPECL, LVDS, LVHSTL, SSTL, HCSL  
REF_CLK accepts the following input levels: LVCMOS, LVTTL  
Input clock frequency range: 6.25MHz to 120MHz  
Maximum output frequency: 480MHz  
The four independent banks of outputs each have their own output  
dividers, which allow the device to generate a multitude of differ-  
ent bank frequency ratios and output-to-input frequency ratios.  
The output frequency range is 25MHz to 480MHz and the input  
frequency range is 6.25MHz to 120MHz. The PLL_EN input can  
be used to bypass the PLL for test and system debug purposes.  
In bypass mode, the input clock is routed around the PLL and into  
the internal output dividers.  
VCO range: 200MHz to 960MHz  
Output skew: 250ps (maximum), outputs at the same frequency  
Cycle-to-cycle jitter: 55ps (maximum)  
LVPECL mode operating voltage supply range:  
V
= 3.135V to 3.465V, V = 0V  
CC  
EE  
ECL mode operating voltage supply range:  
= 0V, V = -3.465V to -3.135V  
V
CC  
EE  
The 873991-147 also has a SYNC output which can be used for  
system synchronization purposes. It monitors Bank A and Bank  
C outputs for coincident rising edges and signals a pulse per the  
timing diagrams in this data sheet. This feature is used primarily  
in applications where Bank A and Bank C are running at different  
frequencies, and is particularly useful when they are running at  
non-integer multiples of each other.  
0°C to 50°C ambient operating temperature  
Available in lead-free (RoHS 6) package  
Use replacement part 873996AYLF  
Example Applications:  
1. Line Card Multiplier: Multiply 19.44MHz from a back-plane  
to 77.76MHz on the line card ASIC and Serdes.  
PIN ASSIGNMENT  
2. Zero Delay Buffer: Fan out up to thirteen 100MHz copies  
from a reference clock to multiple processing units on an  
embedded system.
