LVPECL-TO-LVCMOS / LVTTL FANOUT
BUFFER
FEATURES
GENERAL DESCRIPTION
• 18 LVCMOS/LVTTL outputs, 23Ω typical output impedance
• Selectable LVCMOS_CLK or LVPECL clock inputs
The ICS83940I-01 is a low skew, 1-to-18
ICS
LVPECL-to-LVCMOS/LVTTL Fanout Buffer and a
member of the HiPerClockS™ family of High Per-
formance Clock Solutions from ICS. The
ICS83940I-01 has two selectable clock inputs.
HiPerClockS™
• LVCMOS_CLK supports the following input types:
LVCMOS or LVTTL
The PCLK, nPCLK pair can accept LVPECL, CML or SSTL
input levels. The single ended clock input accepts LVCMOS
or LVTTL input levels. The low impedance LVCMOS/LVTTL
outputs are designed to drive 50Ω series or parallel termi-
nated transmission lines.The effective fanout can be increased
from 18 to 36 by utilizing the ability of the outputs to drive two
series terminated lines.
• PCLK, nPCLK supports the following input types:
LVPECL, CML, SSTL
• Maximum output frequency: 250MHz
• Output skew: 150ps (maximum)
• Part-to-part skew: 750ps (maximum)
• Full 3.3V, 2.5V or mixed 3.3V, 2.5V supply modes
• -40°C to 85°C ambient operating temperature
The ICS83940I-01 is characterized at full 3.3V, full 2.5V and
mixed 3.3V input and 2.5V output operating supply modes. Guar-
anteed output and part-to-part skew characteristics make the
ICS83940I-01 ideal for those clock distribution applications de-
manding well defined performance and repeatability.
• Pin compatible with the MPC940L in single supply
applications

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