ICS511MT - 200MHz PLL Clock Generator | Renesas Electronics
部品番号: ICS511MT ✗ 生産終了ICS511MT 概要
A PLL clock generator, also called a frequency multiplier or clock synthesizer, belongs to the clock and timing IC category. It uses a phase-locked loop to derive an output frequency from a reference source. The reference can be a crystal oscillator or external clock, and the generated CMOS output is suitable for systems requiring a higher-frequency operating clock than the source provides.
Key features of the ICS511MT include PLL clock multiplication, a maximum frequency of 200 MHz, one clock circuit, CMOS output, and support for both crystal and clock inputs. The 1:1 input-to-output ratio is listed for the device, while the PLL architecture provides a practical route to generating a high-frequency clock from a lower-frequency reference. Its single-circuit configuration suits designs requiring one multiplied clock rather than multiple independently generated outputs.
Technically, the ICS511MT is intended for clock generation where the output must be derived from a stable reference. The use of a crystal input supports designs that require predictable frequency behavior, while clock input support allows the device to operate from an existing system reference. The CMOS output interface makes it relevant to digital logic, processor, communications, and embedded-control systems requiring a high-speed clock signal.
Typical applications include clocking for digital processors, communications equipment, test and measurement systems, embedded control platforms, and general-purpose digital logic. The device can reduce the need for multiple external clock-generation solutions when a single high-frequency CMOS clock is sufficient. Its principal benefit is clock multiplication in a small 8-SOIC package, although board-level stability, jitter, supply requirements, and output-drive limits must be checked against the manufacturer datasheet before finalizing a design.
For PCB implementation, place the device close to the crystal, decoupling capacitors, and clock-consuming circuits to minimize trace length and noise pickup. Follow the manufacturer’s recommended crystal load-capacitance network, provide stable supply decoupling, and route the output as a short, controlled-impedance clock trace. Confirm pin orientation, operating limits, and crystal requirements directly from the manufacturer datasheet and the package drawing.
This product summary combines the device’s identified LOCO PLL architecture, 200 MHz maximum frequency, CMOS output, input options, package format, sourcing context, and practical clock-tree design considerations to support faster component selection and PCB planning.

主な用途
ICS511MT の用途: 6 件s: Digital Processor Clocking, Communications Equipment, Embedded Control Systems, Test and Measurement Instrumentation, Industrial Data Acquisition, General-Purpose Digital Logic.
Digital Processor Clocking
The ICS511MT is suited to digital processor clock trees that require a CMOS clock up to 200 MHz derived from a crystal or another clock reference. Its PLL architecture provides frequency multiplication without requiring a separate high-frequency oscillator for every rail. Place the device near the crystal and processor clock input, use the manufacturer-recommended load network, and route the clock output as a short trace. The design must also verify processor setup and hold timing, clock jitter, supply range, and output loading before treating the 200 MHz rating as a complete timing guarantee.
おすすめ
Communications Equipment
The ICS511MT can support communications equipment that needs a stable, high-frequency CMOS clock from a lower-frequency reference. A single PLL clock generator is useful when the board already has a reference source but requires a derived clock for digital signal-processing or interface logic. Keep the reference path short, provide local supply decoupling, and maintain controlled return paths beneath the clock route. Because communications timing can be sensitive to jitter and edge quality, verify the manufacturer’s jitter, output-rise-time, and loading characteristics against the actual downstream device requirements.
おすすめ
Embedded Control Systems
ICS511MT is applicable to embedded-control boards that distribute a CMOS clock to one or more digital logic blocks. Its one-circuit architecture is efficient for a single-clock design, while crystal input support allows the clock generator to serve as the central element of a compact reference network. The board should separate sensitive clock routing from noisy switching nodes, use a solid ground reference, and observe the manufacturer’s crystal load-capacitance calculation. Confirm supply-voltage tolerance and maximum operating frequency for the selected controller before production release.
おすすめ
Test and Measurement Instrumentation
The 200 MHz maximum frequency and CMOS output make ICS511MT relevant to instrumentation clock distribution where a common high-speed reference is needed for counters, converters, or digital control logic. A PLL-based arrangement can consolidate multiple frequency requirements around one reference source, but the exact multiplication ratio and operating conditions must be checked against the device specification. Use short, impedance-controlled clock traces and avoid placing the output route beside high-energy switching nodes. Probe loading and measurement grounding should also be considered during board validation.
おすすめ
Industrial Data Acquisition
ICS511MT can fit industrial data-acquisition systems requiring a deterministic CMOS clock for control, conversion, and communication logic. Its PLL-based reference arrangement can reduce the number of separate oscillator components while supporting either crystal or external-clock operation. Industrial equipment should account for temperature range, supply tolerance, startup behavior, and electromagnetic compatibility at the system level. Place the clock generator close to the reference source, provide the recommended bypass capacitors, and route the output away from switching power stages to minimize coupling.
おすすめ
General-Purpose Digital Logic
For general-purpose digital logic, ICS511MT provides a single CMOS clock output with PLL-based multiplication capability and a maximum listed frequency of 200 MHz. It is most useful when a board already has a stable reference clock and needs a derived output without implementing a high-frequency oscillator network directly on the PCB. Follow the manufacturer’s power-pin and decoupling guidance, confirm input and output logic levels, and reserve the crystal footprint only when the chosen reference configuration requires it. Validate edge quality and load behavior at the intended clock frequency.

設計ノート
Place the ICS511MT near the crystal and clock-consuming circuitry, and keep the clock output trace short. Use a continuous ground reference beneath the clock path, avoid routing parallel to noisy power-converter nodes, and use the manufacturer’s recommended crystal load network. Confirm the 8-SOIC pin orientation and land pattern against the package drawing before fabrication.
Treat the CMOS clock output as a high-speed signal: use a short route, minimize stubs, provide a nearby return path, and maintain consistent geometry where the clock crosses a board boundary. Validate rise time, overshoot, ringing, and downstream load in simulation or with an oscilloscope. The 200 MHz maximum-frequency rating alone does not establish timing margin for a particular receiver.
Do not select an ICS511-family substitute from the series name alone. Confirm the exact MPN, pin assignment, input-source configuration, maximum frequency, supply range, and delivery suffix against the manufacturer datasheet. In particular, ICS511MI is listed at 160 MHz versus 200 MHz for ICS511MT, making it unsuitable for designs that require the full target frequency.
Follow the manufacturer’s power-pin connection and decoupling layout for the ICS511MT. Place the required bypass capacitor immediately adjacent to the device supply pin and provide an unobstructed ground return. Check the device’s current consumption and supply operating limits in the datasheet; those values were not present in the available product summaries and must not be assumed for a new design.
