ICS87946AYI-147LFT Clock Generators & Support Products 10 LVCMOS OUT  BUFFER/DIVIDER

Description

The ICS87946I-147 is a low skew, +1, +2 LVCMOS/LVTTL Clock
Generator. The ICS879461-147 has two selectable single ended
dlock inputs. The single ended clock inputs accept LVCMOS or
LVTTL input levels. The low impedance LVCMOS/LVTTL outputs are
designed to drive 502 series or parallel terminated transmission
lines. The effective fanout can be increased from 10 to 20 by uilizing
the ability of the outputs to drive two series terminated lines.
The divide select inputs, DIV_ SEL x, control the output frequency of
each bank. The outputs can be tilized in the +1, +2 ora
combination of +1 and +2 modes. The master reset input, MR/nOE,
resets the internal frequency dividers and also controls the active
and high impedance states of all outputs.
The ICS87946I-147 is characterized at full 3.3V for input Voo, and
mixed 3.3V and 2.5V for output operating supply mode. Guaranteed
bank, output and part-to-part skew characteristics make the
ICS87946I-147 ideal for those clock distribution applications
demanding well defined performance and repeatability.

ICS87946AYI-147LFT is a model of clock generator IC (Integrated Circuit) manufactured by Integrated

Device Technology (IDT). It is designed to provide clock generation and distribution capabilities with

10 low-voltage CMOS (LVCMOS) output buffers/dividers.

Here are some key features and characteristics of the ICS87946AYI-147LFT clock generator:

1. Clock Generation and Distribution: The ICS87946AYI-147LFT enables the generation and distribution

of clock signals within electronic systems. It can generate multiple output clocks from a single input

clock source.

1. LVCMOS Output Buffers/Dividers: The IC provides 10 output buffers/dividers that support LVCMOS

signaling. LVCMOS is a low-voltage signaling standard commonly used for digital interfaces in modern

electronic systems.

1. Frequency Generation and Division: The clock generator allows for frequency generation and division.

It can generate output clocks with different frequencies by dividing the input clock frequency.

1. Low Jitter Performance: Jitter refers to the variation in the timing of clock signals, and minimizing jitter

is important for maintaining reliable and stable timing within a system. The ICS87946AYI-147LFT is

designed to provide low jitter output clocks, ensuring accurate and consistent timing.

1. Supply Voltage: The IC operates with a supply voltage typically ranging from 2.5V to 3.3V. This makes

it compatible with standard power supply levels used in many electronic systems.

1. Package and Pin Compatibility: The IC is available in a specific package and follows industry-standard

pin configurations. This allows for ease of integration into existing circuit board designs and simplifies

the design process.

The ICS87946AYI-147LFT is primarily used in applications where clock distribution and synchronization

are critical, such as communication systems, networking equipment, and high-performance computing.

It provides a convenient solution for generating and distributing clock signals with low jitter performance.
