ICS309R 概要
A clock synthesizer generates or distributes one or more related clock signals for digital systems. This ICS309R belongs to the PLL-based clock generator hierarchy: it compares a reference clock with an internal phase-locked loop and then divides or multiplies that reference to produce programmable outputs. Spread-spectrum clocking reduces the concentration of clock energy at one frequency, while serial programming permits controlled configuration by an embedded controller.
The strongest verified features of ICS309R are its triple-PLL architecture, serial programmability, spread-spectrum operation, 200 MHz maximum frequency, LVCMOS output type, and support for both clock and crystal reference sources. The bypass function can be useful when a system must pass through or test a clock source without normal PLL operation. The 20-pin surface-mount SSOP supports compact clock-generation layouts.
The supplied snippets do not disclose the complete PLL configuration ranges, individual output-channel assignments, jitter specifications, serial interface levels, or output-drive details. Engineers should therefore treat ICS309R as a 200 MHz-class, 3.3 V clock synthesizer and verify every timing and signal-integrity requirement against the manufacturer datasheet before releasing a new design. Some retrieved summaries appear to mix ICS309R with the closely related ICS308, so this distinction is important.
Typical uses include processor and controller clock generation, communications equipment, storage systems, test and measurement instruments, and embedded systems that require programmable frequency generation or spread-spectrum clocking. In each case, the reference clock, target output frequency, loop filter, serial programming sequence, and downstream load must be validated together.
PCB implementation should preserve short, controlled-impedance clock paths and provide clean return paths beneath the device. Keep programming signals away from sensitive clock nets, observe all bypass-capacitor recommendations in the datasheet, and confirm output rise and fall times at the actual receiver. Do not infer pin function or output assignment from the family-level product description alone.
This page consolidates the verified distributor and datasheet-index information available for ICS309R, separates confirmed facts from missing data, and provides replacement, selection, and design guidance that is not presented as a manufacturer datasheet replacement.

主な用途
ICS309R の用途: 6 件s: Embedded Processor Clock Generation, Communications Equipment Timing, Test and Measurement Instrumentation, Industrial Control Systems, Data Acquisition and Conversion Systems, Networking and Storage Clock Distribution.
Embedded Processor Clock Generation
ICS309R fits an embedded processor clock-generator position because it combines a clock or crystal reference input with a programmable PLL architecture and LVCMOS outputs reaching 200 MHz. A host controller can use the serial interface to configure required timing relationships rather than relying on a fixed-frequency oscillator. Before adoption, confirm the target processor's frequency range, input capacitance, startup sequence, jitter tolerance, and exact output assignment. The verified data does not map the three PLLs to physical outputs, so clock-tree design must follow the exact manufacturer pinout and programming table.
おすすめ
Communications Equipment Timing
ICS309R is suitable for communications equipment that benefits from programmable clock generation, PLL-based frequency conversion, and spread-spectrum operation. A reference clock or crystal can feed the synthesizer, while LVCMOS outputs distribute the generated timing within a line card or module. Spread spectrum can reduce the peak spectral concentration of a clock signal, although the permitted modulation profile and downstream clock quality are not provided in the excerpts. Confirm frequency range, jitter, output-drive, I/O levels, and regulatory needs before selecting it for a new communications platform.
おすすめ
Test and Measurement Instrumentation
ICS309R can support instrumentation architectures that need programmable or multiple PLL-derived timing domains. Serial programmability allows a controller to configure clock frequencies as operating modes change, while the stated 200 MHz ceiling accommodates high-speed digital sections. However, test equipment often has unusually strict phase-noise, jitter, isolation, calibration, and amplitude requirements that are not confirmed in the supplied search snippets. Use the device only after measuring those parameters and validating clock-edge quality with the actual receiver, cables, and test circuitry.
おすすめ
Industrial Control Systems
ICS309R can provide programmable clocking in industrial controllers, data-acquisition modules, and factory automation equipment where several digital subsystems may require related but distinct timing. Its 3.0 V to 3.6 V supply range and 20-pin SSOP package suit compact 3.3 V designs, subject to operating-temperature qualification. Industrial use also demands attention to clock jitter, supply noise, ground references, and lifecycle status. The verified data does not state the temperature range or AEC-Q100 status, so neither qualification nor long-term availability should be assumed.
おすすめ
Data Acquisition and Conversion Systems
ICS309R may serve as a local clock synthesizer in data-acquisition systems that need configurable digital timing alongside converters. The PLL architecture can derive system timing from a reference, and spread-spectrum support may help spread clock energy when appropriate for the system. Signal-chain designers must still evaluate deterministic and random jitter at the relevant output frequency, because the supplied records provide only the 200 MHz maximum. Confirm converter input-frequency limits, clock duty-cycle requirements, output-channel assignments, and logic thresholds before final schematic approval.
おすすめ
Networking and Storage Clock Distribution
ICS309R can be evaluated for clock generation inside networking or storage equipment that requires programmable frequency domains, bypass capability, and spread-spectrum clock control. A reference clock can be multiplied or divided through the PLL architecture, while LVCMOS outputs support digital logic integration. Real adoption demands careful examination of output channel routing, source-to-output ratios, jitter, crosstalk, and termination. Since those details are absent from the verified snippets, treat ICS309R as a candidate rather than a fully specified drop-in network-clock solution.

設計ノート
Use a verified ICS309R pinout before routing the board. The supplied records confirm SSOP-20 packaging but do not expose individual pin assignments, and one retrieved description incorrectly discusses a quad-PLL device. Cross-check every power, ground, reference-clock, serial-programming, and clock-output connection against the exact manufacturer datasheet before PCB release.
Route every clock output as a short, controlled-impedance trace with a continuous return path. The verified data specifies LVCMOS outputs and a maximum frequency of 200 MHz, but it provides no rise/fall time, drive strength, jitter, or crosstalk data. Measure edge quality at the receiver and include receiver loading, trace length, terminations, and supply noise in the timing budget.
Do not merge ICS309R documentation with ICS308 material. One supplied result attributes a quad-PLL, six-output description to a related part, while verified ICS309R records identify a triple-PLL device. Lock the documentation revision and part number, then verify PLL count, output assignments, programming register behavior, and supply limits before schematic sign-off.
ICS309R operates from 3.0 V to 3.6 V, so design the rail around those exact limits rather than assuming a wider range. Apply the manufacturer’s bypass and decoupling requirements to the relevant supply pins. Because internal current consumption and output-drive data are not present in the supplied records, calculate power and clock loading only after obtaining the complete datasheet and worst-case operating conditions.
コンプライアンス情報
The supplied search records do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status.
