ICS411MT - 25MHz LVCMOS PC Clock Generator | Renesas
MPN: ICS411MT ✓ Hoạt độngICS411MT Tóm tắt
A clock generator is a timing IC that converts an input reference into one or more stable clock signals for digital systems. Clock synthesizers sit within the clock and timing IC family, where phase-locked loops (PLLs) can multiply, divide, or otherwise condition a reference frequency. Within a computer platform, the resulting clock can synchronize bus activity, interface circuits, peripheral controllers, and other logic that must operate from a common timing reference.
Key characteristics of the ICS411MT include its PLL capability, clock input, LVCMOS output, maximum operating frequency of 25 MHz, and single-circuit architecture. These features make the part relevant to legacy PC motherboard and peripheral clocking where a compact integrated solution is preferred over multiple discrete timing components. Its 8-pin SOIC package also supports conventional surface-mount assembly and automated PCB production.
Technically, the ICS411MT combines reference-clock conditioning with PLL-based frequency generation. A PLL synchronizes an output phase to a reference signal while permitting frequency synthesis through internal loop control. This architecture is useful when the board must derive a required operating clock from an available reference while maintaining a defined relationship between input and output. The manufacturer datasheet is the controlling document for loop bandwidth, jitter, operating limits, pin functions, and electrical characteristics.
Typical applications include PC motherboard clock generation, peripheral interface timing, clock distribution for legacy computer logic, and replacement of discrete oscillator-and-divider networks. The device can also serve systems in which one LVCMOS clock domain must be reproduced for multiple downstream circuits. Board designers should verify timing margins, output drive, supply requirements, and all enable or feedback connections against the manufacturer datasheet before production.
The primary design consideration is to treat the clock as a high-speed signal even though its maximum frequency is only 25 MHz. Route the output with a short, controlled-impedance path, keep the reference and output returns connected to a common ground plane, and place decoupling capacitors close to the supply pins. Avoid unnecessary stubs and test-probe loops that can degrade edge quality or introduce reflections.
This page consolidates the verified clock-generator specifications, package information, sourcing workflow, pinout status, and engineering guidance for ICS411MT evaluation. It also distinguishes documented functionality from parameters that must be confirmed in the manufacturer datasheet, helping engineers assess fit before committing to a PCB or production release.

Ứng dụng tiêu biểu
ICS411MT phù hợp cho 6 Áp dụngs: PC Motherboard Clock Generation, Legacy Peripheral Interface Timing, Computer Bus Clock Distribution, LVCMOS Clock Reference Distribution, Industrial Control Clock Module, Legacy Digital Logic Clocking.
PC Motherboard Clock Generation
The ICS411MT fits legacy PC motherboard clock-generation requirements because it combines PLL capability, a clock input, an LVCMOS output, and one clock circuit in an 8-pin SOIC package. According to the ICS411MT manufacturer datasheet, the device was developed as a cost-effective solution intended to reduce component count in motherboard and peripheral clocking. A board designer can use the PLL to establish the required relationship between the available reference and the generated clock. The design must still confirm the supported input and output frequencies, supply voltage, feedback arrangement, output duty cycle, and timing margins against the manufacturer datasheet before layout release.
Legacy Peripheral Interface Timing
The ICS411MT is suitable for legacy peripheral interface timing when the subsystem needs a compact, PLL-based LVCMOS clock rather than a full-size standalone oscillator and divider network. Its one-circuit architecture and maximum frequency of 25 MHz fit clock domains within that range. According to the ICS411MT manufacturer datasheet, the ICS411MT targets PC peripheral applications, allowing it to provide a central timing reference for interface controllers or associated digital logic. The key design checks are reference-to-output frequency ratio, clock edge quality, load capacitance, and whether the generated waveform meets the receiving device’s setup and hold requirements.
Computer Bus Clock Distribution
Use the ICS411MT as the clock-generation element feeding a legacy computer bus or adjacent logic when the board requires a generated LVCMOS clock with PLL relationship to a system reference. The documented single clock circuit, PLL capability, and 25 MHz maximum frequency make it practical for timing domains below that limit. According to the ICS411MT manufacturer datasheet, the device’s intended PC and peripheral focus supports this role. Validate source impedance and fanout because output drive, duty-cycle distortion, and loading can affect edge integrity even when the nominal clock frequency remains compliant.
LVCMOS Clock Reference Distribution
The ICS411MT can serve an LVCMOS clock-reference node in a mixed legacy digital system where a common reference must feed several synchronized blocks. Its PLL-based clock generation allows the board to create a controlled clock from an upstream source, while the SOIC-8 package simplifies conventional surface-mount routing. According to the ICS411MT manufacturer datasheet, the part is a one-circuit clock generator intended for motherboard and peripheral use. Keep the source-to-output path short, provide a low-impedance return plane, and confirm maximum loading and timing specifications before adding clock branches or test points.
Industrial Control Clock Module
The ICS411MT may support a compact clock module within legacy industrial-control electronics when the controller logic requires a stable LVCMOS reference and the system remains within the documented 25 MHz maximum. Its PLL capability is useful for deriving a required clock relationship without a collection of oscillator and divider parts, while the one-circuit architecture simplifies board allocation. According to the ICS411MT manufacturer datasheet, the device was developed for PC motherboard and peripheral applications, so industrial use requires careful review of operating temperature, supply limits, clock accuracy, and lifecycle expectations before production qualification.
Legacy Digital Logic Clocking
The ICS411MT can clock a group of legacy digital logic blocks that share a PLL-synchronized reference and operate below the documented 25 MHz limit. Its LVCMOS output and eight-pin SOIC package provide a compact implementation, while PLL-based generation offers more flexibility than a fixed-frequency oscillator. According to the ICS411MT manufacturer datasheet, the device targets PC motherboard and peripheral timing systems. Before implementation, check every receiver’s setup and hold timing, ensure the reference and feedback network follows the recommended configuration, and account for clock skew across the routed traces.

Ghi chú thiết kế
Route the reference input, feedback path, and LVCMOS clock output as short, controlled-impedance traces on a continuous ground plane. The ICS411MT operates up to 25 MHz, but excessive stubs, vias, and probe loops can still degrade edge quality. Follow the pin-configuration and recommended-layout diagrams in the manufacturer datasheet, and avoid routing unrelated digital signals beneath the clock outputs to reduce coupling.
Do not assume that every clock generator with a 25 MHz maximum is interchangeable with the ICS411MT. Confirm the SOIC-8 pin assignments, supply voltage, reference-input range, PLL configuration, output enable behavior, output duty cycle, and feedback requirements from the manufacturer datasheet. A generic fixed-frequency oscillator also may not reproduce the required relationship between the input reference and the generated LVCMOS clock.
Account for trace capacitance, receiver input capacitance, and output loading when fanning out the LVCMOS clock. Keep the clock source close to the first receiving logic and use a defined ground reference beneath the route. Validate edge rate and duty-cycle distortion with the final load because a clock that meets its nominal frequency can still create setup or hold failures when edges are distorted.
