ICS2402M - Multiplier Zero Delay Buffer | Renesas
Teilenummer: ICS2402M ✓ AktivICS2402M Übersicht
A zero-delay buffer, or ZDB, is a clock and timing semiconductor that combines frequency multiplication or conditioning with buffered clock propagation. In the broader product hierarchy, ICS2402M belongs to clock and timing ICs and ultimately to the semiconductor category. Unlike a passive resistor-and-capacitor delay line, an active ZDB uses PLL techniques to establish the output relationship and provide a low-delay clock output.
The verified product information identifies the ICS2402M as a multiplier and zero-delay buffer, with one LVCMOS output and a single-ended signal arrangement. The 8-SOIC package supports conventional surface-mount PCB assembly. Verified distributor information also identifies the component as lead-free and RoHS compliant. Exact operating limits, supply-voltage range, supported multiplication ratios, frequency range, output impedance, and timing tolerances were not present in the supplied source excerpts and therefore require confirmation from the manufacturer datasheet before design release.
Technically, the ICS2402M integrates analog and digital PLL methods to multiply a reference clock while buffering the result. This architecture is intended to reduce the timing penalty normally encountered when a system must distribute a clock derived from a lower-frequency reference. The single-ended LVCMOS interface can simplify connection to conventional digital logic, but signal-integrity review remains necessary because PLL multipliers can amplify supply noise and produce clock-related harmonics.
Typical uses include processor and communications clock generation, frequency-interface bridging, industrial data-acquisition systems, and retrofit designs requiring a clock output derived from an existing reference. In each case, the designer must confirm that the selected multiplier ratio, input frequency, output frequency, and supply voltage fall within the limits documented for the exact ICS2402M ordering configuration.
For implementation, begin by reviewing the pin assignment and recommended decoupling in the manufacturer datasheet, then validate the output waveform with the intended clock load. Keep the clock trace short where possible, provide a clean return path, and account for PLL lock and startup behavior in the system timing budget. Because the verified excerpts do not provide the complete timing table, board release should be conditional on checking the official electrical characteristics and reference circuit.
This product record combines verified device identity, package, interface, regulatory, and sourcing information with application-specific design guidance. It also separates confirmed facts from parameters that remain unavailable, helping engineers distinguish source-backed characteristics from values that still require datasheet confirmation.

Processor Clock Frequency Multiplication
The ICS2402M fits systems that need a clock derived from a lower-frequency reference for processor, controller, or programmable-logic timing. Its verified multiplier and zero-delay-buffer function uses proprietary analog/digital PLL techniques rather than a passive delay network, while the single-ended LVCMOS output provides a conventional digital clock interface. The 8-pin SOIC package also keeps the implementation in a standard surface-mount footprint. Before deployment, confirm that the reference frequency, required multiplication ratio, output frequency, supply voltage, and timing limits all satisfy the manufacturer datasheet; those numerical limits were not present in the supplied excerpts.
Communications Clock Distribution
ICS2402M can be evaluated for communications equipment that requires a stable multiplied clock at an internal logic interface. The PLL-based zero-delay-buffer architecture is relevant where a reference oscillator must feed multiple clock domains or where clock conditioning is needed before distribution. The verified one-output, single-ended LVCMOS interface simplifies connection to digital circuitry, and the 8-pin SOIC package supports conventional assembly. However, one output limits fan-out compared with a multi-output buffer, so downstream distribution may require another stage. Validate jitter, skew, output loading, and supply-noise behavior against the official datasheet before release.
Industrial Data-Acquisition Timing
The ICS2402M is suitable for investigation in industrial data-acquisition and control systems that need a derived timing signal alongside an external reference. Its multiplier capability can reduce the number of independent oscillators required, while the zero-delay-buffer stage is intended to regenerate the clock for digital control logic. The confirmed single-ended LVCMOS output is compatible with a conventional clock-input arrangement, subject to voltage-level and timing checks. Because the verified excerpts do not state the operating-temperature range, supply range, or frequency limits, the part should remain a conditional choice until those requirements are confirmed from the manufacturer datasheet.
Test and Measurement Instrumentation
ICS2402M may be used in clock-conditioning or frequency-conversion blocks within test and measurement equipment. A PLL-based multiplier can generate a derived clock from a stable reference, while the buffered output supports downstream digital control or conversion logic. The verified 8-pin SOIC package is appropriate for compact surface-mount assemblies. Care is required because the device has one single-ended LVCMOS output, so a multi-clock instrument may need additional distribution or fan-out components. Verify propagation delay, jitter, reference-input sensitivity, and supply decoupling using the official application circuit and electrical-characteristics tables before choosing it for precision instrumentation.
LED and Mixed-Signal Timing Interface
The ICS2402M can serve as a clock-generation interface in LED controllers, display timing systems, or mixed-signal products that require a deterministic digital timing reference. Its zero-delay-buffer function is more appropriate than a passive delay line when the design needs a regenerated output, and the single-ended LVCMOS interface can feed compatible control logic. The 8-pin SOIC package offers a conventional assembly option for compact boards. Designers should still account for the one-output architecture, check output drive against the selected load, and confirm whether the supply and frequency range cover the intended operating environment using the manufacturer datasheet.
Clock-Frequency Interface Bridging
ICS2402M is relevant when an existing system uses one reference-clock domain but an adjacent logic block requires a multiplied clock. The PLL-based zero-delay-buffer function can place the derived clock close to the destination logic and provide a buffered LVCMOS output, helping isolate the timing interface from the source distribution network. Because only one single-ended output is verified, each additional clock destination may require a separate buffer or a different multi-output device. The design should not be released until the supported ratio, lock behavior, startup time, output impedance, and supply requirements have been verified from official documentation.

Wichtigste Unterscheidungsmerkmale

- Uses a single-ended LVCMOS clock interface (vs. Differential clock-buffer options)
- Available in a compact conventional surface-mount package (vs. Larger clock-generator packages)
Designhinweise
Confirm the permitted supply range, power dissipation, and decoupling configuration in the manufacturer datasheet before enabling the PLL. A PLL-based clock multiplier can respond to supply noise, so use the shortest practical input, output, and ground paths and follow the reference layout exactly. Keep sensitive analog return current separate from switching-node returns where the board design permits, and verify power-up behavior before relying on a valid clock at system reset.
Treat the ICS2402M output as a clock signal even though it uses a single-ended LVCMOS interface. Route it over a continuous reference plane, avoid stubs and test-point discontinuities, and terminate according to the actual edge rate and load. Place decoupling capacitors close to the device pins and provide a short ground return. PCB trace length and impedance can materially affect timing because the manufacturer data excerpts do not supply complete board-layout or output-loading guidance.
Do not treat the family name 2402 or the presence of the M suffix as proof that another ordering code is interchangeable. The verified material for 2402MLFT does not confirm its package, pinout, electrical limits, or lifecycle status. Also do not substitute the ICS2402MT search result as an alternative because it may differ only by shipping format. Validate the actual clock ratios, supply range, output loading, and timing requirements against the official ICS2402M datasheet.
Compliance-Informationen
The verified distributor listing states that ICS2402M is lead-free and RoHS compliant. No verified AEC-Q100, REACH, halogen-free, or conflict-minerals declaration was supplied; not_applicable is used for AEC-Q100 because the available information does not identify this clock IC as an automotive-qualified device.
