ICS501G 概要
A PLL-based clock generator multiplies or conditions a lower-frequency reference to produce a stable, high-frequency clock for digital logic, processors, communications equipment, and embedded systems. The ICS501G belongs to the broader clock and timing hierarchy: oscillator and crystal support → clock generator → PLL clock multiplier → digital timing subsystem. Its CMOS output and 160MHz maximum frequency suit moderate-speed digital clocking requirements, although timing margins must be checked for the selected operating condition.
Key verified attributes include PLL operation, one clock-generator circuit, a 1:1 input-to-output ratio in the cited specification summary, and no differential input or output. The available package information is 8-TSSOP or 8-MSOP, depending on the orderable package variant represented by the ICS501G family listing. The exact electrical limits, crystal-load details, output-drive capability, jitter, and recommended decoupling requirements were not supplied in the verified excerpts and must be confirmed in the manufacturer datasheet before layout release.
Typical uses include microcontroller and processor clock generation, digital interface timing, embedded control systems, and communications modules requiring a local high-frequency reference. The device is intended to replace conventional crystal-oscillator arrangements in suitable electronic systems, according to the Renesas product description. Designers should account for supply voltage, output load, trace impedance, grounding, and the timing relationship between the generated clock and downstream circuitry.
A key design consideration is to validate the reference clock and PLL configuration against the exact datasheet before production. Keep the oscillator and feedback paths short, provide a clean return path, and place required decoupling capacitors close to the supply pins. Because the verified data does not state the full pinout, pin names, or package-specific ordering details, those values remain subject to datasheet verification.
This page consolidates verified distributor specifications, official Renesas datasheet information, application guidance, and drop-in replacement constraints into an engineering-focused component record for sourcing and design review.

主な用途
ICS501G の用途: 8 件s: Microcontroller Clock Generation, Digital Communications Interface, Processor Timing Reference, Industrial Control Module, FPGA Support Circuit, Embedded Oscillator Replacement, Clock Distribution Hub, Consumer Embedded Device.
Microcontroller Clock Generation
The ICS501G fits embedded systems that need a local CMOS clock generated from a crystal or external reference. Its verified PLL architecture and 160MHz maximum frequency make it suitable for processor timing, peripheral clocking, and control-loop synchronization. Place the reference network and required bypass capacitance close to the device, then route the clock to the destination with controlled impedance. Confirm the exact PLL configuration, startup behavior, duty cycle, and timing budget in the Renesas datasheet before release.
おすすめ
Digital Communications Interface
Use the ICS501G where a communications module needs a local single-ended CMOS clock source derived from a lower-frequency reference. The verified no-differential-input and no-differential-output ratings make it appropriate for conventional CMOS logic rather than direct LVDS or HSTL signaling. The 160MHz ceiling supports moderate-speed digital timing, but the designer must verify edge rate, jitter, load, trace length, and downstream receiver margins for the selected interface.
おすすめ
Processor Timing Reference
The PLL-based ICS501G can provide a centralized CMOS clock for processors, controllers, and digital peripherals that must operate from a common reference. Because the verified specification identifies a 1:1 input-to-output ratio, use it where the reference arrangement and PLL configuration are appropriate rather than assuming arbitrary multiplication. Validate clock-domain relationships, maximum frequency at the target voltage, and startup sequencing across every connected device.
おすすめ
Industrial Control Module
ICS501G is applicable to compact industrial control boards that distribute a local clock to logic, sensors, and interface circuits. The 3V-to-5.25V verified supply range supports mixed 3.3V and 5V design exploration, while the surface-mount package preserves board area. Industrial temperature, noise, and EMC requirements must be checked separately because the supplied excerpts do not state the operating-temperature or EMC ratings.
おすすめ
FPGA Support Circuit
The ICS501G can supply a single-ended CMOS clock to suitable FPGA or digital-logic blocks after the required frequency and timing conditions are verified. PLL conditioning may help organize the reference architecture, but it does not replace a dedicated high-performance clock transceiver for high-jitter-sensitive or differential-clock requirements. Route the output away from switching nodes, provide a continuous ground reference, and check FPGA clock-input thresholds before using the device.
おすすめ
Embedded Oscillator Replacement
The ICS501G is positioned by Renesas as a cost-effective replacement for crystal oscillators in most electronic systems. It is useful when the design benefits from a PLL clock generator, CMOS output, and crystal or external-clock input rather than a standalone resonator oscillator. Validation should include startup time, frequency accuracy, load capacitance, temperature stability, supply sensitivity, and the exact package variant before production substitution.
おすすめ
Clock Distribution Hub
Use the ICS501G as the source stage in a small clock-distribution arrangement where several CMOS domains need a common reference. Its single CMOS output is suitable for driving an appropriately buffered fan-out network, but the IC should not be assumed to drive long or heavily loaded traces without checking output-current and edge-rate specifications. Keep stub lengths short, terminate unused branches according to the clock architecture, and preserve a low-impedance return path.
おすすめ
Consumer Embedded Device
The ICS501G is suitable for compact consumer and hobby electronics that require a local CMOS clock and can operate within the verified 3V-to-5.25V supply range. It may simplify clock architecture relative to multiple discrete oscillator arrangements, but cost-effective substitution depends on availability and package choice. Confirm the exact MPN suffix, operating temperature, load capacitance, and required output frequency before using it in a consumer product.

主な差別化要因
- PLL-based clock generation with 160MHz maximum frequency （vs A fixed crystal oscillator)
- Single-ended CMOS architecture （vs A differential clock generator)
- Compact surface-mount options （vs A larger through-hole oscillator package)
- Broad verified supply-voltage range （vs A narrow single-rail oscillator option)
設計ノート
Keep the crystal, oscillator support components, PLL loop elements, and decoupling network close to the ICS501G according to the manufacturer reference layout. The verified data identifies crystal or clock input but does not provide the complete pinout or loop-component values, so do not finalize placement from generic guidance alone. Preserve short return paths and avoid routing the sensitive clock path beside switching nodes or high-current digital edges.
The ICS501G output is listed as single-ended CMOS rather than differential. Treat the clock as a high-speed single-ended signal: use a continuous reference plane, minimize stubs, control trace geometry, and verify receiver thresholds with the actual load. If the destination requires differential clocking, add an appropriate buffer or transceiver rather than assuming the ICS501G output can be connected directly.
Use the verified 3V-to-5.25V supply range only after checking the exact datasheet limits and output load. Place required bypass capacitors at the supply pins with short, low-inductance connections, and account for ground bounce when the clock generator shares a board with switching regulators or high-current digital circuits. Estimated: if the downstream system requires a 5V rail, the device is within the verified upper limit; operating margin must still be checked against temperature and load.
Do not confuse the 8-TSSOP and 8-MSOP package names with interchangeable footprints. Verify the exact orderable suffix, pin numbering, and package drawing for the selected variant. Also avoid assuming that the 160MHz maximum applies at every supply voltage, temperature, output load, or reference configuration. Validate startup, frequency accuracy, jitter, and downstream timing with the final crystal or external-clock network.
コンプライアンス情報
The supplied verified excerpts do not contain RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. Compliance status must be confirmed from the exact manufacturer product documentation and orderable variant.
