IFFERENTIAL-TO-2.5V/3.3V/5V LVPECL/ECL RECEIVER  
GENERAL DESCRIPTION  
FEATURES  
The ICS853017 is a quad 1-to-1, 2.5V/3.3V/5V dif- 4 differential LVPECL / ECL 1:1 receivers  
ICS  
ferential LVPECL/ECL receiver and a member of  
4 differential LVPECL clock input pairs  
the HiperclocksTM family of High Performance Clock  
HiPerClockS™  
Solutions from ICS.The ICS853017 operates with  
a positive or negative power supply at 2.5V, 3.3V or  
PCLKx, nPCLKx pairs can accept the following  
differential input levels: LVPECL, LVDS, CML, SSTL  
5V, and can accept both single-ended and differential inputs.For  
single-ended operation, an internally generated voltage, which is  
available on output pinVBB, can be used as a switching bias volt-  
age on the unused input of the differential pair.VBB can also be  
used to rebias AC coupled inputs.  
Output frequency: >2GHz (typical)  
Translates any single ended input signal to  
LVPECL levels with resistor bias on nPCLKx input  
Output skew: TBD  
Part-to-part skew: TBD  
Propagation delay: 320ps (typical)  
LVPECL mode operating voltage supply range:  
VCC = 2.375V to 5.25V  
ECL mode operating voltage supply range:  
VCC = 0V, VEE = -5.25V to -2.375V  
-40°C to 85°C ambient operating temperature  
Pin compatible with MC100LVEL17

APPLICATION INFORMATION  
WIRING THE DIFFERENTIAL INPUT TO ACCEPT SINGLE ENDED LEVELS  
Figure 1 shows how the differential input can be wired to accept of R1 and R2 might need to be adjusted to position theV_REF in  
single ended levels. The reference voltage V_REF ~ VCC/2 is the center of the input voltage swing. For example, if the input  
generated by the bias resistors R1, R2 and C1.This bias circuit clock swing is only 2.5V andVCC = 3.3V, V_REF should be 1.25V  
should be located as close as possible to the input pin.The ratio and R2/R1 = 0.609.

The clock layout topology shown below is a typical termina-

are recommended only as guidelines.  
50transmission lines. Matched impedance techniques should  
be used to maximize operating frequency and minimize signal  
distortion. Figures 2A and 2B show two different layouts which  
are recommended only as guidelines. Other suitable clock lay-  
outs may exist and it would be recommended that the board  
designers simulate to guarantee compatibility across all printed  
circuit and clock component process variations.  
FOUT and nFOUT are low impedance follower outputs that gen-  
erate ECL/LVPECL compatible outputs.Therefore, terminating  
resistors (DC current path to ground) or current sources must  
be used for functionality. These outputs are designed to drive
