ICS341MP - 200MHz Spread Spectrum Clock Synth | Renesas
MPN: ICS341MP ✓ AktifICS341MP Genel Bakış
A field-programmable clock synthesizer is a clock-and-timing IC that generates a stable digital clock from an external reference. The ICS341 belongs to the broader PLL-based frequency synthesizer hierarchy, where the PLL multiplies or divides a reference frequency to create a programmable operating clock. Clock-and-timing ICs support digital systems requiring deterministic frequency generation, clock distribution, or reduced electromagnetic interference.
The ICS341MP supports spread-spectrum clock generation to reduce system EMI by distributing clock energy over a range of frequencies. Its maximum frequency is 200 MHz, while its minimum programmable output is 250 kHz. A single LVCMOS output simplifies clock routing, and the integrated PLL allows the device to operate from a clock or crystal reference. These characteristics suit designs that need adjustable timing without a complex multi-output clock architecture.
The ICS341MP is implemented in an 8-SOIC surface-mount package measuring 3.90 mm in body width. This package provides a practical upgrade over larger through-hole clock devices while remaining compatible with conventional PCB assembly. Its single-circuit architecture also keeps the signal path manageable, although applications requiring multiple independently programmable outputs would need a more capable clock generator.
Typical uses include EMI-sensitive embedded systems, communications equipment, consumer electronics, and digital processing platforms where a programmable reference is useful. Spread-spectrum operation can help reduce narrowband emissions in systems that must meet internal or regulatory EMC goals. The 200 MHz ceiling supports common processor, interface, and control-clock requirements, while the 250 kHz lower limit accommodates lower-rate digital buses and control logic.
Designers should verify the reference-input configuration, programmed frequency range, output enable behavior, and external crystal or clock requirements against the manufacturer datasheet before layout. Keep the reference and output paths short, provide the required decoupling capacitors close to the device, and confirm that the selected spread-spectrum range satisfies both timing margins and system EMC objectives.
This page organizes the ICS341MP specifications, sourcing information, design guidance, and qualified drop-in options into one engineering-focused reference. It supports faster part selection while emphasizing the need to validate programming, reference, and EMC details against the manufacturer datasheet.

EMI-Sensitive Embedded Systems
The ICS341MP fits embedded platforms that require a programmable clock with optional spread-spectrum operation to reduce narrowband electromagnetic emissions. According to the manufacturer datasheet, the device provides one LVCMOS output covering 250 kHz to 200 MHz from a clock or crystal reference. Place it close to the clock-consuming circuitry, preserve a short reference path, and confirm that spreading does not consume the available timing margin. Its single-output architecture simplifies implementation compared with a multi-output clock generator, while the 8-SOIC package keeps the footprint compact for space-constrained control boards.
Önerilen
Communications Equipment
The ICS341MP is appropriate for communications equipment needing a flexible reference clock with output frequencies from 250 kHz to 200 MHz. According to the manufacturer datasheet, the integrated PLL and programmable LVCMOS output allow the system clock to be adjusted for multiple interface or processing requirements. Spread-spectrum support can help disperse concentrated clock energy that would otherwise contribute to narrowband emissions. The design must still be checked for reference jitter, output duty-cycle requirements, and EMC margin, because those operating details are not reproduced in the basic product summary.
Önerilen
Consumer Electronics
The ICS341MP can supply a compact programmable clock for consumer-electronics boards where a single LVCMOS output is sufficient. According to the manufacturer datasheet, the ICS341 family supports output frequencies from 250 kHz to 200 MHz and can use spread-spectrum techniques to reduce system EMI. The 8-SOIC package supports conventional surface-mount assembly without requiring a large multi-output clock device. For successful integration, confirm the exact pin assignments, reference-input method, output-enable behavior, and required decoupling directly from the manufacturer documentation.
Önerilen
Digital Control and Processor Platforms
The ICS341MP is useful as a programmable clock source for embedded processors, controllers, and digital peripherals operating below its 200 MHz maximum output frequency. According to the manufacturer datasheet, the device accepts either a clock or crystal input, includes one PLL, and provides a 1:1 input-to-output ratio. Programmable frequency selection provides flexibility across board revisions, while optional spreading can reduce concentrated EMI. Validate jitter, clock-edge tolerance, and startup behavior against each connected device because those specifications must be established from the complete manufacturer datasheet.
Önerilen
Industrial Control Equipment
The ICS341MP can support industrial control boards that need a stable, programmable LVCMOS clock and controlled EMI behavior. According to the manufacturer datasheet, its output spans 250 kHz to 200 MHz and may employ spread-spectrum techniques to reduce system interference. The single-output device is straightforward to integrate when one clock domain is required. Industrial designs should verify the device's electrical and temperature limits from the manufacturer documentation, then review grounding and return paths so the clock signal retains the edge quality expected by the downstream logic.
Önerilen
Test and Measurement Products
The ICS341MP can serve as a programmable reference clock in test and measurement equipment requiring adjustable rates within the 250 kHz-to-200 MHz range. According to the manufacturer datasheet, it generates one LVCMOS output and supports spread-spectrum techniques when reduced narrowband emissions are useful. A single output keeps the clock distribution path compact, while the 8-SOIC package facilitates board-level integration. Before using the device as a precision reference, confirm output accuracy, jitter, duty-cycle behavior, and reference requirements in the full manufacturer datasheet.

Tasarım Notları
Place the ICS341MP close to the circuit that consumes its LVCMOS clock, and route the output with a short, continuous path away from high-current switching nodes. Position the required input and bypass capacitors adjacent to their associated pins using the manufacturer layout recommendations. Keep the crystal or clock-reference route short, symmetrical, and isolated from noisy digital and power-conversion paths to reduce coupling into the PLL.
Use spread-spectrum operation when the system benefits from reduced narrowband clock energy, but review the permitted modulation range and center frequency before committing the timing design. According to the manufacturer datasheet, the ICS341MP supports spread-spectrum techniques for reducing system EMI. Spread the clock only after confirming that downstream setup and hold timing remain valid across the complete frequency excursion.
Do not select the ICS341MP solely by its 200 MHz headline specification. Confirm the reference-input type, programming method, supply-voltage limits, operating-temperature grade, output-enable behavior, and exact pin assignments in the manufacturer datasheet. Also verify whether a crystal or external clock is appropriate for the design; incorrect reference configuration can prevent startup even when the requested output frequency is inside the stated range.
