ICS511MI - 160MHz Single PLL Clock Generator | Renesas
MPN： ICS511MI ✗ 停產ICS511MI 概覽
A clock generator is an integrated timing device that converts a reference clock or crystal into one or more stable timing signals. Within the broader semiconductor hierarchy, the ICS511MI is a PLL clock generator, a clock and timing IC, and ultimately a power-management-adjacent frequency-generation component. Its single-channel structure simplifies designs that require a local high-frequency clock rather than a more complex multi-output timing architecture.
The ICS511MI provides a maximum operating frequency of 160 MHz, accepts either clock or crystal input, and produces a CMOS output. The listed input-to-output ratio is 1:1, indicating that the generated output frequency corresponds directly to the supplied reference relationship. Its operating temperature range extends from -40°C to +85°C, allowing operation across industrial temperature environments when the external reference and load conditions meet the device requirements.
Internally, the device uses a single PLL to multiply or organize a lower-frequency reference into a higher-frequency clock. This approach offers a practical alternative to relying solely on a high-frequency external oscillator when the system requires a locally generated, specified timing signal. The one-circuit implementation also reduces board area compared with solutions containing several clock-generation channels.
Typical applications include communication equipment, digital signal-processing systems, frequency conversion, clock multiplication, and general digital subsystems requiring a local CMOS clock. The ICS511MI is particularly relevant to compact designs where an 8-pin surface-mount package and a single clock output are preferred over a larger multi-channel timing device.
Designers should select the reference frequency and external loop-filter components according to the manufacturer recommendations, then verify output jitter and acquisition behavior across the intended frequency range. Board layout should keep the crystal or clock path short, provide a clean return path, and place support components close to the device to reduce susceptibility to noise and parasitic feedback.
This product page combines the ICS511MI device identity, verified operating parameters, packaging information, drop-in comparison candidates, and practical design guidance. It also highlights the distinctions that matter when evaluating clock-frequency range, package compatibility, reference input method, and application suitability before making a replacement decision.

典型應用
ICS511MI 適用於 6 應用s: Communication Equipment Clocking, Digital Signal Processing, Frequency Multiplication, Industrial Control Modules, Data Acquisition Systems, Clock-Cleaning Subsystems.
Communication Equipment Clocking
The ICS511MI fits communication equipment that needs a local CMOS clock generated from a crystal or lower-frequency reference. Its single-PLL architecture and 160 MHz maximum operating frequency support digital signal-chain and control subsystems without a multi-output timing device. The 8-pin SOIC package simplifies placement, although the reference network and loop-filter values must follow the manufacturer recommendations. Confirm that the required output frequency, jitter, supply voltage, and clock load remain within the device limits.
推薦
Digital Signal Processing
The ICS511MI can provide the local timing reference for a digital signal-processing subsystem that requires up to 160 MHz from a crystal or clock input. Its 1:1 ratio and CMOS output make it relevant to processors, converters, and programmable logic operating from a common local clock domain. Because a PLL-based generator can amplify reference noise and phase error, the reference source and loop-filter selection should be evaluated for the target signal chain.
推薦
Frequency Multiplication
The ICS511MI is designed for clock-multiplication applications that use a PLL to develop a higher-frequency CMOS clock from a lower-frequency crystal or source. This is useful when designing a compact subsystem around the device's 160 MHz maximum operating frequency and 1:1 relationship. The implementation should reserve appropriate routing for the reference and feedback networks, and validation should cover startup, lock behavior, jitter, and output stability across temperature.
推薦
Industrial Control Modules
The ICS511MI supports timing requirements in compact industrial control modules operating across the stated -40°C to +85°C range. A single clock channel and 8-pin SOIC package can simplify board usage where one local CMOS clock is sufficient for control logic, converters, or interface devices. Industrial designs should account for reference tolerance, temperature-dependent crystal behavior, supply integrity, and the device's acquisition behavior at the intended operating frequency.
推薦
Data Acquisition Systems
A local ICS511MI clock can support data-acquisition subsystems in which converters and digital processing must operate from a consistent timing source. The CMOS output and single-PLL implementation are suitable for a compact architecture, while the 160 MHz ceiling provides a defined upper operating boundary. For precision conversion systems, validate output jitter against the converter's acquisition requirements and keep the clock return path short to minimize coupling into the analog section.
推薦
Clock-Cleaning Subsystems
The ICS511MI can serve as a local clock-generation stage in systems where a reference source is distributed and each subsystem requires its own CMOS clock. Its single PLL can organize the reference into a defined output relationship, reducing dependence on multiple high-frequency oscillators. Designers should characterize phase noise, output jitter, and loop behavior rather than assuming that nominal frequency matching guarantees signal-integrity equivalence.

主要差異化特點

- Documented 1:1 input-to-output relationship (對比PI6C4511WE)
- Compact single-channel implementation (對比511MLF)
設計說明
Keep the crystal, reference input, PLL loop-filter components, and clock output traces short. Route the clock over a continuous ground plane, avoid crossing noisy power or digital switching paths, and place decoupling capacitance close to the device supply pins. These practices reduce parasitic sensitivity, reference jitter, and unwanted feedback in the PLL loop.
Validate acquisition time, output jitter, and clock stability at the lowest and highest intended frequencies. A maximum operating frequency of 160 MHz does not by itself establish acceptable timing quality for every downstream device. Use an oscilloscope or dedicated clock-analysis instrument to examine the output waveform and test across temperature and supply conditions.
Do not select a replacement based only on the 8-pin SOIC package and clock-generator description. Before substituting the 511MLF or PI6C4511WE, compare pin assignments, supported input range, supply voltage, loop-filter values, output-jitter limits, and startup behavior. The alternatives reach 200 MHz, but frequency capability alone does not establish pin-to-pin compatibility.
