Programmable Clock Devices
The 5V9885 integrates spread spectrum generation and 3 independent PLLs,
each with very granular multipliers and dividers
IDT Programmable Clock Devices
The IDT family of programmable clocks
includes an advanced set of clock generation
and distribution devices that support in-system
programming and test. These devices can be
configured or reconfigured at any point during
the manufacturing process or end product’s
life cycle. This versatility, coupled with an
advanced architecture and feature set, provides
a compelling proposition to every segment of
IDT customers. Designers benefit from these
devices’ high-resolution PLLs, broad feature set

can utilize the in-system programming and
test capabilities to reduce their costs and
cycle times. Supply-chain managers enjoy a
marked reduction in inventory complexity and
cost as well as the potential to extend product
life cycles through the non-volatile program-
ming capability.

IDT creates preemptive semiconductor
solutions that accelerate packet pro-
cessing for advanced network services.
By anticipating the needs of equipment
designers in the core, metro, access,
enterprise, small office/home office
(SOHO), data center and wireless seg-
ments of the network, IDT has created
an industry-leading portfolio of semicon-
ductor ICs. Our clock distribution and
generation products enable the best
performance in high-speed telecommuni-
cation, networking and storage area
network equipment by offering leading-
edge I/O standards and precise, reliable
timing performance. We also offer network
search engines (NSEs), flow-control
management ICs (FCMs), multi-protocol
switch fabric and traffic management
chipsets, the Interprise™ family of inte-
grated communications processors,
FIFOs, multi-ports, and telecommunica-
tions ICs, as well as high-performance
digital logic ICs and high-speed SRAM
devices. Use IDT solutions to accelerate
and enhance your network equipment
designs.
is based on an innovative three-PLL archi-
tecture that includes ultra-high-resolution
prescalers, multipliers and output dividers.
With VCO ranges up to 1.1 GHz, nearly
any combination of clock scaling ratios
from a single input frequency is possible.
The IDT5V9885 can replace multiple crystal
oscillators and is ideal in any system that
requires clock frequency translation or mul-
tiple clock domains. Leading-edge features
such as programmable spread spectrum
generation and glitchless input switching
provide additional tools to the designers of
next-generation clock networks.
Development and evaluation kits for the
entire family are available. Please contact
your local IDT sales representative.
