ICS252PM - 200MHz Dual-Output Clock Synthesizer | Renesas
MPN: ICS252PM ✓ فعالICS252PM جائزہ
A clock synthesizer is a clock-and-timing integrated circuit that generates or distributes one or more related clock signals. In the broader hierarchy, ICS252PM belongs to the clock generator and frequency synthesizer family, within clock and timing ICs and ultimately the semiconductor category. Its dual-output architecture can reduce the number of separate oscillator and distribution components required in a system.
The verified product information identifies ICS252PM as a low-cost, field-programmable, dual-output clock synthesizer capable of generating two output frequencies from 314 kHz to 200 MHz. The 200 MHz upper limit makes the device applicable to communication equipment, storage systems, computer peripherals, and other systems requiring a programmable clock. Spread-spectrum operation can reduce peak spectral concentration, although exact modulation settings and implementation limits must be confirmed in the manufacturer datasheet.
The ICS252PM uses independently programmable output stages rather than a fixed-frequency oscillator arrangement. This allows one device to serve multiple clock domains when two related but unequal frequencies are required. Because it is a digital-programmable clocking component, board design should account for trace propagation, output loading, supply integrity, and EMI behavior associated with high-frequency clock distribution.
The part is offered in an 8-SOIC package, providing a conventional surface-mount footprint for PCB assembly. In an 8-SOIC, the exact pin names, programming interface, supply voltage, output-drive capability, operating-temperature range, and electrical limits are not supplied in the verified excerpts and are therefore identified as data needed rather than estimated.
Typical uses include clock generation for networking and communication equipment, read/write timing in storage systems, industrial control electronics, and embedded computing platforms. Validate the required frequency range, jitter, skew, supply voltage, and output configuration against the complete manufacturer datasheet before releasing a production design.
This product record combines verified distributor identification, package and frequency information, sourcing links, application guidance, and practical selection criteria. It distinguishes explicitly verified facts from parameters that still require confirmation, helping engineers avoid unsupported assumptions while locating an ICS252PM replacement or equivalent.

Networking Equipment Clock Generation
The ICS252PM fits networking equipment that requires two programmable clocks in one device because it generates independently programmed frequencies from 314 kHz to 200 MHz. The dual-output architecture can replace separate fixed oscillators when related clock domains are needed for communication interfaces, control logic, or data-conversion stages. Spread-spectrum operation may also reduce concentrated clock-spectrum peaks, depending on the selected modulation parameters. Before implementation, verify supply voltage, jitter, output skew, drive strength, and logic thresholds in the complete datasheet, and confirm that the two outputs can accommodate the intended loads without external buffers.

Storage Controller Timing
The ICS252PM is suitable for storage-controller timing blocks where programmable clocks up to 200 MHz are useful and two related outputs can reduce oscillator count. One output may serve a controller or memory interface while the other supports a different internal clock domain, subject to the device's verified configuration limits. Spread-spectrum generation can help broaden the energy distribution of a periodic clock and reduce narrowband peaks. The critical design checks are storage-interface timing, jitter, skew, I/O voltage, and trace loading; all four must be confirmed from the full manufacturer datasheet and interface specifications.

Industrial Control and Automation
The ICS252PM can support industrial control and automation systems requiring programmable timing up to 200 MHz and two output domains. Its field-programmable synthesis permits frequency changes without physically replacing a fixed oscillator, which is useful when the same controller board supports different sensor, communications, or actuator timing plans. Spread-spectrum clocking may assist electromagnetic-interference control, but its effectiveness depends on the programmed deviation and modulation rate. Confirm supply range, temperature limits, output jitter, and pin-compatible interface voltage before industrial deployment, and test clock behavior across the full board-level temperature range.
تجویز کردہ
Communication Interface Timing
The ICS252PM is appropriate for communication-interface timing where a system must generate two related clocks and can operate below the verified 200 MHz maximum. Programmable output frequencies allow one synthesizer to accommodate multiple interface domains rather than imposing one fixed clock across the design. The dual outputs may feed a communications controller, data converter, or transceiver domain, provided the frequency ratio and output configuration meet the manufacturer limits. For a production design, review jitter, skew, duty-cycle distortion, clock-crossing margins, and edge-rate requirements against the relevant communications standard before relying on the nominal 200 MHz capability.

Test and Measurement Equipment
The ICS252PM can serve as a programmable timing source in test and measurement equipment requiring repeatable dual clocks up to 200 MHz. Field programming allows different clock plans to be configured for multiple test modes, while spread-spectrum capability offers an additional spectral-control option for sensitive measurements or EMC-related benches. Instrument designers must account for reference-clock accuracy, jitter transfer, output symmetry, channel-to-channel skew, and termination requirements. Because the supplied verified excerpts do not provide the complete timing or jitter limits, a laboratory characterization should verify the programmed frequencies and waveform integrity across temperature and supply variation.

Embedded Computing Clock Tree
The ICS252PM can contribute to an embedded-computing clock tree when the design needs two programmable frequencies rather than one fixed reference. A 200 MHz ceiling supports moderately fast digital domains, and the field-programmable architecture can simplify boards that support multiple operating modes. The synthesizer does not remove the need for good power and signal integrity: supply decoupling, ground return paths, trace length matching, output loading, and downstream fanout must be controlled. Check the exact output enable, programming, and supply pins in the datasheet, and validate that the selected clock frequencies meet processor, memory, and peripheral timing requirements.

ڈیزائن نوٹس
Treat both clock outputs as high-speed signals. Route each output over a continuous reference plane, minimize stubs and unnecessary vias, and use a source termination scheme appropriate to the receiver's input impedance. Confirm edge rate, duty-cycle distortion, jitter, and maximum capacitive loading from the complete datasheet before assigning trace length or fanout. Differential trace length matching is not necessarily required for a single-ended clock, but round-trip skew and downstream setup-and-hold timing must remain within the receiving device's limits.
Place the ICS252PM close to the clock-consuming circuits and keep the oscillator or reference path as short as practical. Separate clock traces from sensitive analog inputs and high-current switching paths, and maintain uninterrupted ground beneath the device. Follow the manufacturer's recommended input, output, and bypass-capacitor connections exactly; the verified excerpts do not specify capacitor values, so do not infer them from generic clock-generator designs.
Spread-spectrum clocking may reduce narrow spectral peaks, but it does not replace good layout practices. Configure the modulation rate and percentage using the manufacturer-supported limits, and measure both clock fundamentals and harmonics at the required EMI test conditions. Pay particular attention to edge-current harmonics, package/trace radiation, and cable-connected clock outputs because these can dominate emissions even when the fundamental spectrum appears improved.
Do not treat a nominal 200 MHz maximum as proof that every output can run continuously at 200 MHz under every load and supply condition. Verify configuration limits, output frequency accuracy, duty cycle, output loading, supply tolerance, and temperature range in the complete manufacturer datasheet. When replacing ICS252PM, compare pin names and functions rather than package drawing alone, because two 8-SOIC clock devices can use otherwise identical footprints for incompatible programming or clocking schemes.
