ICS511M - 200MHz LOCO PLL Clock Generator | Renesas Electronics
N.º de pieza: ICS511M ✓ ActivoICS511M Descripción general
A clock generator is a timing IC that converts a stable low-frequency reference into a higher-frequency clock required by digital logic, communications equipment, processors, and interface circuits. A phase-locked loop, or PLL, is the feedback-based clock architecture used in the ICS511M. In this product hierarchy, ICS511M is a clock generator with PLL capability, belonging to the clock and timing IC family within integrated circuits and power-management-adjacent digital systems. The LOCO product family is intended to provide economical frequency multiplication and clock distribution functions.
The principal verified specifications include a maximum frequency of 200 MHz, one clock circuit, PLL operation, clock or crystal input, and CMOS output. These characteristics make ICS511M suitable for systems that require a local high-frequency clock without using a dedicated high-speed processor clock tree. The 8-SOIC package supports conventional surface-mount assembly and is distinct from larger leaded packages. The 3.135 V minimum and 5.25 V maximum supply limits place it in a low-voltage digital supply range.
The typical clock-generation topology connects a crystal or external clock source to the input, configures the PLL multiplication ratio, and feeds the resulting CMOS clock into the target digital subsystem. This arrangement can reduce the number of high-frequency clock sources required across a board while centralizing frequency generation. Compared with a free-running oscillator, the PLL approach allows the output frequency to be related to an external reference. Compared with a microprocessor that includes an internal PLL, ICS511M provides a separate timing source that can be shared by multiple functional blocks when the circuit design allows it.
ICS511M can be used in communications equipment, digital control systems, embedded processing platforms, clocked logic, and industrial or consumer electronics requiring a stable high-frequency reference. Designers should verify the complete input-frequency range, output-frequency limits, jitter, duty-cycle, timing, and loop-filter requirements against the manufacturer datasheet before finalizing a design. Those parameters are not present in the supplied verified web data and must be confirmed before production use.
This page combines verified distributor and manufacturer references, the available LOCO-series identification, a package-level comparison framework, and practical selection guidance. It also distinguishes verified information from parameters that require datasheet confirmation, helping engineers evaluate ICS511M without treating generic PLL or clock-generator claims as part-specific facts.

Aplicaciones típicas
ICS511M es adecuado para 6 aplicacións: Communications Equipment Clocking, Digital Control System Timing, Embedded Processor Clock Reference, Clocked Logic and Interface Timing, Industrial Data-Acquisition System, Consumer and Industrial Digital Products.
Communications Equipment Clocking
ICS511M fits communications equipment requiring a local high-frequency clock derived from a crystal or lower-frequency reference. Its verified PLL capability, 200 MHz maximum output frequency, and CMOS output provide a practical basis for digital transmit, receive, or data-processing subsystems. The circuit can place the ICS511M near the clocked logic to keep the generated clock distribution controlled. Design confirmation is essential because the supplied data does not specify jitter, duty-cycle error, reference-input range, or output skew. The system designer should also verify loop stability, crystal load capacitance, and acquisition behavior using the Renesas 511 datasheet.
Recomendado
Digital Control System Timing
ICS511M is suitable for digital control systems that need a stable, locally generated clock instead of relying on a distant system-wide timing source. The verified 200 MHz maximum frequency allows it to address processor, logic, and data-conversion clock requirements, while the PLL can multiply a suitable lower-frequency reference. In a controller, the generated CMOS clock can feed compatible timing domains after level and fan-out checks. Because output loading, jitter, duty cycle, and sequencing details are not included in the supplied data, engineers must validate the clock topology, fan-out, trace loading, and power-supply noise margin before production release.
Recomendado
Embedded Processor Clock Reference
ICS511M can serve as a dedicated reference generator beside an embedded processor when the design benefits from a separate clock source. The device accepts a crystal or clock input and uses PLL multiplication to generate up to 200 MHz, giving a design option for clocking processors, memory interfaces, and programmable logic. Locating the generator close to the intended load may improve routing flexibility, although actual jitter and edge quality remain unverified in the supplied material. Before adoption, confirm that the output meets the processor's timing, supply, and clock-mode requirements and that the PLL configuration remains stable over temperature and supply variation.
Recomendado
Clocked Logic and Interface Timing
ICS511M provides a focused solution for clocked logic blocks that need a higher-frequency CMOS clock derived from a shared low-frequency reference. Its one-circuit PLL arrangement and 200 MHz maximum output make it relevant to interfaces, counters, and data-pipeline logic where a central reference must be multiplied. Using a common reference can simplify synchronization across several functional blocks. The implementation should account for clock-tree topology, maximum fan-out, trace impedance, return-path continuity, and endpoint input capacitance. Because those timing details are not specified in the verified search data, simulation and datasheet review are required before choosing component values or fan-out limits.
Recomendado
Industrial Data-Acquisition System
ICS511M is applicable to industrial data-acquisition systems that coordinate sampling, control, and communication blocks from a stable reference. The verified 200 MHz ceiling provides headroom for timing-intensive digital processing, while the crystal or clock input permits synchronization with other equipment. The device should be placed according to the final clock-tree architecture so that sensitive processing paths receive short, controlled traces. Production designs must confirm jitter, duty cycle, supply sensitivity, and operating-temperature limits, none of which are quantified in the supplied verified data. Environmental testing and power-integrity checks are especially important when the acquisition platform is adjacent to motors, relays, or switching converters.
Recomendado
Consumer and Industrial Digital Products
ICS511M can support consumer or industrial digital products that require an economical local clock generator with a 200 MHz maximum output. Its 8-SOIC package is compatible with conventional surface-mount PCB assembly, and its CMOS output suits many digital clock trees. A system designer can use a crystal or distributed reference and configure the PLL to derive the required local frequency. The verified information does not cover startup time, holdover, jitter, supply noise rejection, or output drive capability, so the device should not be approved solely from the headline frequency rating. Confirm those parameters and test worst-case startup and clock-accuracy behavior across the intended voltage and temperature range.

Notas de diseño
Keep the crystal or reference clock path short and route it away from high-slew-rate switching nodes. Place the reference-source components and their ground returns close to ICS511M according to the manufacturer application circuit. Maintain a continuous return path beneath clock traces, and avoid routing the sensitive reference net beneath power inductors, transformers, or digital bus layers.
Decouple the 3.135 V to 5.25 V supply with the capacitance and placement specified in the Renesas 511 datasheet. Keep the regulator and clock-generator supply connections short, use low-ESR ceramic bypass capacitors, and provide a quiet ground connection. Validate supply-noise tolerance and startup behavior across the intended supply range because those values are not included in the supplied verified data.
Treat the generated CMOS clock as a controlled-impedance signal. Match trace geometry to the intended load and termination scheme, minimize stub lengths, and account for receiver capacitance and fan-out. Check rise time, ringing, duty-cycle distortion, and clock-to-clock skew on the assembled PCB. Use endpoint or source termination only after validating it against the actual receiver and clock topology.
Do not assume that two 8-SOIC clock generators are interchangeable because their outlines match. Confirm pin names, reference-input range, PLL multiplication limits, supply voltage, output-drive capability, jitter, and operating-temperature range against the manufacturer datasheets. Also verify the ordering suffix and shipping form because the verified Hotenda listing identifies tube packaging while other inventory channels may use different forms.
