GENERAL DESCRIPTION
FEATURES
The ICS8516I is a low skew, high performance • 16 Differential LVDS outputs
ICS
1-to-16 Differential-to-LVDS Clock Distribution
• CLK, nCLK pair can accept the following differential
input levels: LVPECL, LVDS, LVHSTL, HCSL, SSTL
HiPerClockS™
Chip and a member of the HiPerClockS™
family of High Performance Clock Solutions
from ICS. The ICS8516I CLK, nCLK pair can
• Maximum output frequency: 700MHz
accept any differential input levels and translates them to
3.3V LVDS output levels. Utilizing Low Voltage Differential
Signaling (LVDS), the ICS8516I provides a low power, low
noise, point-to-point solution for distributing clock signals
over controlled impedances of 100Ω.
• Translates any differential input signal (LVPECL, LVHSTL,
SSTL, DCM) to LVDS levels without external bias networks
• Translates any single-ended input signal to LVDS
with resistor bias on nCLK input
Dual output enable inputs allow the ICS8516I to be used in
a 1-to-16 or 1-to-8 input/output mode. Guaranteed output
and part-to-part skew specifications make the ICS8516I ideal
for those applications demanding well defined performance
and repeatability.
• Multiple output enable inputs for disabling unused
outputs in reduced fanout applications
• LVDS compatible
• Output skew: 65ps (maximum)
• Part-to-part skew: 550ps (maximum)
• Propagation delay: 2.4ns (maximum)
• 3.3V operating supply
• -40°C to 85°C ambient operating temperature

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 the
V_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.

LVDS DRIVER TERMINATION
A general LVDS interface is shown in Figure 2. In a 100Ω dif-
ferential transmission line environment, LVDS drivers require
a matched load termination of 100Ω across near the receiver
input. For a multiple LVDS outputs buffer, if only partial out-
puts are used, it is recommended to terminate the un-used
outputs.

DIFFERENTIAL CLOCK INPUT INTERFACE
The CLK /nCLK accepts LVDS, LVPECL, LVHSTL, SSTL, HCSL gested here are examples only. Please consult with the vendor
and other differential signals. Both VSWING and VOH must meet of the driver component to confirm the driver termination re-
the VPP and VCMR input requirements. Figures 3A to 3E show quirements. For example in Figure 3A, the input termination
interface examples for the HiPerClockS CLK/nCLK input driven applies for ICS HiPerClockS LVHSTL drivers. If you are using
by the most common driver types. The input interfaces sug- an LVHSTL driver from another vendor, use their termination
recommendation.
