ICS502M Обзор
A clock generator, also called a clock multiplier or PLL clock generator, converts a lower-frequency reference into one or more higher-frequency timing signals. Within the broader clock and timing hierarchy, the ICS502M belongs to the oscillator family, the clock-generator family, and ultimately the timing-control IC category. Its phase-locked loop compares the reference with a divided feedback signal, adjusts the internal oscillator, and produces a stable multiplied output. This architecture makes it useful in systems needing a clock rate that is inconvenient or unavailable from a discrete crystal.
Key verified features include a maximum output frequency of 190 MHz, input-frequency support from 2 MHz to 50 MHz, low jitter of 50 ps one sigma, and operation from 3.0 V to 5.5 V. The output can support 25 mA drive capability at TTL levels. Duty-cycle behavior is specified at 45/55 through 160 MHz, which is relevant when clocking TTL-compatible logic. The advanced low-power CMOS process supports portable and embedded equipment where clock generation must combine compactness with controlled power consumption.
The ICS502M is suited to CPU and digital-logic clocking, communications equipment, test and measurement systems, industrial controls, and embedded platforms that can tolerate the deterministic jitter of a PLL-derived clock. Because PLL multiplication depends on the reference and feedback configuration, board-level layout, supply integrity, loop stability, and output loading can influence signal quality. The 8-pin SOIC package is straightforward to assemble but requires careful decoupling close to the supply pins and short, controlled clock routes to minimize added noise and skew.
Designers should verify the required multiplication ratio, output frequency, duty-cycle limits, jitter budget, supply voltage, and downstream load before finalizing a design. They should also compare the PLL-derived output against the phase-noise requirements of any receiver, serializer, processor, or ADC. The manufacturer datasheet remains the authoritative source for programming details, timing characteristics, electrical limits, and the complete pin assignment.
This page consolidates the verified manufacturer and distributor information for ICS502M, adds application-specific engineering context, and identifies same-package alternatives where the available cross-reference data supports direct replacement. It also distinguishes verified facts from parameters that still require confirmation from the complete datasheet or application-specific testing.

CPU and Embedded Digital Clocking
The ICS502M fits CPU clocking when a system needs a higher-frequency timing reference than its available crystal can directly provide. Its verified input range of 2 MHz to 50 MHz, output capability up to 190 MHz, and 45/55 duty-cycle operation through 160 MHz support common digital timing requirements. The PLL-based architecture provides a compact alternative to implementing a discrete oscillator and multiplier stage. Before deployment, compare the downstream processor's clock-jitter tolerance with the device's 50 ps one-sigma specification, confirm edge polarity, and keep the clock route short to avoid additional skew.
Рекомендуется
Communications and Network Equipment
The ICS502M can supply a multiplied clock for communications equipment where a compact, high-frequency reference is required. Its PLL clock-multiplier function operates from 3.0 V to 5.5 V and produces outputs as high as 190 MHz, making it relevant to digital transport, interface, and controller blocks. The principal engineering concern is jitter: the verified 50 ps one-sigma value should be compared with the receiver or serializer's total jitter budget, including reference noise and board-added jitter. Controlled supply decoupling and an uninterrupted clock path help preserve usable signal integrity in compact network hardware.
Рекомендуется
Industrial Control and Automation
For industrial controls, the ICS502M offers a compact way to derive a high-frequency clock from a lower-frequency reference while operating from standard 3.3 V or 5 V rails. Its surface-mount 8-pin SOIC package simplifies board assembly, and the verified 190 MHz maximum output covers demanding digital-control blocks. Industrial designs should still assess electromagnetic-emissions and clock-sensitivity constraints: route the output away from sensitive analog sections, provide local supply bypassing, and validate timing margins across temperature, supply, and load. The PLL's reference-to-output relationship should also be checked against the controller's specified clock tolerance.
Рекомендуется
Test and Measurement Instrumentation
The ICS502M is appropriate for compact test and measurement modules that need a stable high-frequency clock without allocating board area to a large discrete oscillator assembly. Verified operation from 3.0 V to 5.5 V supports common instrument architectures, while 50 ps one-sigma jitter is relevant to moderate-speed digital measurement paths. For precision analog and phase-sensitive instrumentation, engineers should evaluate the complete phase-noise and jitter spectrum rather than relying only on the one-sigma figure. A clean reference, short output trace, adequate decoupling, and an output-load arrangement compatible with the 25 mA TTL-level drive specification are essential design considerations.
Рекомендуется
Consumer and Portable Electronics
The ICS502M can support compact consumer electronics that require a multiplied digital clock while operating from a 3.3 V or 5 V supply. Its low-power CMOS implementation and 8-pin SOIC package balance functionality with board-area efficiency. For battery-powered products, total power depends on supply voltage, output activity, loading, and the selected PLL configuration, so the system designer should measure it rather than infer consumption from process technology alone. Keep the reference oscillator mechanically isolated from vibration sources and route the high-frequency output away from sensitive analog and radio-frequency sections to minimize coupling.
Рекомендуется
Data Acquisition and Sensor Processing
ICS502M is suitable for clocking data-acquisition and sensor-processing electronics that need a high-speed internal timing reference but have limited board space. Outputs up to 190 MHz provide margin for digital control paths, while the 3.0 V to 5.5 V supply range supports embedded and industrial rails. Signal-chain performance depends on keeping the PLL clock away from analog inputs and maintaining a stable reference. Designers should establish a timing budget for the converter, sensor interface, and processor, and verify that the selected duty cycle and jitter remain acceptable under the actual loading and supply conditions.

Заметки по проектированию
Place the ICS502M close to the device that consumes the multiplied clock and keep the output trace short and continuous. Avoid routing the high-frequency output beneath noisy power or switching-node areas. A short path reduces capacitive loading, radiation, and sensitivity to trace delay while helping preserve usable clock edge quality.
Use the manufacturer-prescribed bypass capacitors and place them adjacent to the supply and ground pins. Keep the loop formed by the decoupling network, package ground connections, and power plane as small as practical. Because PLL clock jitter can be affected by reference and supply noise, verify operation with realistic supply ripple rather than relying only on a quiet laboratory supply.
Create a timing budget that includes the ICS502M's 50 ps one-sigma jitter, reference-source noise, board-added jitter, load-dependent edge distortion, and downstream device tolerance. Check the selected output frequency against the verified 190 MHz maximum and the 45/55 duty-cycle range through 160 MHz. Confirm receiver polarity and edge requirements before committing to the clock topology.
Do not treat 502MLF as an automatic substitution without reviewing the complete Renesas documentation. The supplied comparison says its terminals, package, and principal characteristics are consistent, but it does not provide a full table of multiplier ranges, programming details, jitter, or duty cycle. Validate the exact operating mode, reference configuration, and load behavior with manufacturer samples.
Информация о соответствии
The supplied verified data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is marked not applicable because the device is presented as a general clock-generator IC rather than an automotive-qualified variant.
