ICS503M - 160MHz LOCO PLL Clock Generator | Renesas Electronics
MPN: ICS503M ✓ Hoạt độngICS503M Tóm tắt
A PLL clock multiplier is a timing IC that multiplies a lower-frequency reference into a higher-frequency clock. This clock generator belongs to the broader hierarchy of oscillator and clock ICs, frequency synthesizers, timing devices, and semiconductors. The LOCO family was designed as a cost-effective way to produce a high-quality, high-frequency clock when the source frequency is substantially lower than the required system clock.
The ICS503M's primary documented specifications are its 160 MHz maximum clock-generator frequency and single-output configuration. Its 8-SOIC surface-mount package provides a compact implementation for communication, networking, industrial, and digital-system clock trees. The 3.90 mm package width is explicitly stated by the distributor listing, while additional electrical limits and detailed timing characteristics were not included in the provided verified extraction.
The LOCO architecture separates clock generation from the frequency source. A low-frequency crystal or external clock can be multiplied by the internal PLL to produce the required output frequency. PLL-based generation can reduce the cost and size of the frequency reference compared with using a high-frequency resonator, although loop filter selection, reference stability, output jitter, and startup behavior must be evaluated in the target design.
Typical uses include generating a high-frequency communication clock from a lower-frequency reference, supporting digital processors and programmable logic, and clocking interface or data-conversion systems. The ICS503M can also serve as a clock-tree element where one low-frequency source must be multiplied before distribution to multiple downstream circuits.
Designers should confirm the complete pinout, reference-input range, output waveform, supply voltage, output drive, jitter, lock behavior, and stability requirements against the manufacturer datasheet before layout release. Because only summary distributor specifications were provided, these implementation-critical values remain deliberately unresolved rather than estimated.
This page combines the verified 160 MHz, single-output, and 8-SOIC package information with traceability to the available distributor and datasheet listings. It also distinguishes confirmed data from unavailable parameters, provides application-oriented engineering context, and avoids presenting unsupported pin assignments, prices, or substitution claims as verified facts.

Ứng dụng tiêu biểu
ICS503M phù hợp cho 6 Áp dụngs: Communication Interface Clocking, Processor and Programmable Logic Timing, Industrial Control and Automation, Network Equipment Clock Trees, Data Acquisition and Conversion Systems, Test and Measurement Instrumentation.
Communication Interface Clocking
The ICS503M is appropriate for communication subsystems that derive a high-frequency operating clock from a lower-frequency crystal or clock reference. Its verified 160 MHz maximum frequency and single-output architecture allow a compact timing block to support serializers, deserializers, transceivers, and controller-side logic. The PLL multiplier approach can reduce reliance on a separate high-frequency resonator while retaining a stable reference relationship. Before implementation, verify the required output waveform, jitter, supply voltage, and load capability in the manufacturer datasheet because those values were not present in the supplied extraction.
Được đề xuất
Processor and Programmable Logic Timing
The ICS503M can supply a multiplied clock to processors, programmable logic, or other digital subsystems when a low-frequency reference is available. Its 160 MHz capability covers demanding control and data-path clock domains, while the 8-SOIC package keeps the timing circuit compact. A PLL-based source also permits flexible frequency generation relative to the crystal frequency. The system designer should still account for clock distribution loss, jitter tolerance, startup time, and the relationship between reference accuracy and output accuracy when establishing the complete timing budget.
Được đề xuất
Industrial Control and Automation
The ICS503M is suitable for industrial control boards that need a compact, high-frequency clock derived from a common low-frequency reference. A single 160 MHz clock can support high-speed control logic, sampling systems, or industrial communication blocks while avoiding a separate high-frequency crystal oscillator. The surface-mount 8-SOIC package also works well with automated assembly. Industrial designs must confirm operating-temperature limits, supply tolerances, jitter, and long-term reference stability from the full datasheet because the supplied records do not establish those industrial environmental limits.
Được đề xuất
Network Equipment Clock Trees
The ICS503M can serve as the source element in a network-equipment clock tree when one multiplied clock must be distributed to multiple functional blocks. Its 160 MHz output capability is relevant to packet-processing, physical-layer, and control-plane circuitry, while the LOCO PLL structure allows use of a cost-effective low-frequency reference. One output limits fanout without additional buffering, so the clock tree should include appropriately characterized distribution or fanout components. Confirm output drive, jitter, and edge-rate requirements against the actual network interface before design freeze.
Được đề xuất
Data Acquisition and Conversion Systems
The ICS503M can generate the high-frequency reference used by sampling, data-conversion, or digital signal-processing subsystems. Multiplying a lower-frequency crystal permits a compact clock source for systems whose sampling rate requires up to 160 MHz. The single-output arrangement is most appropriate when one derived clock can be distributed locally or used to drive additional timing circuitry. Designers should evaluate jitter and reference-to-output stability as part of the converter's acquisition budget, while using the 8-SOIC footprint to preserve board area for analog and signal-conditioning components.
Được đề xuất
Test and Measurement Instrumentation
The ICS503M can provide a compact multiplied clock for instrumentation that needs a stable reference-derived timing signal without a separate high-frequency resonator. A 160 MHz source may support counters, timing controllers, digital measurement engines, and high-speed control logic. Its small 8-SOIC footprint leaves more board area for analog front ends, signal conditioning, and display interfaces. Measurement accuracy remains dependent on reference quality and clock jitter, so the design must include adequate filtering, distribution, and output-loading analysis based on the complete manufacturer datasheet.

Ghi chú thiết kế
Place the crystal or clock-source network, PLL loop-filter components, supply decoupling, and clock output routing according to the manufacturer reference layout. The verified ICS503M package is 8-SOIC, but its individual pin functions were not included in the supplied data. Do not assign or route pins from this page; verify the official pin table and recommended layout first to avoid mismatched oscillator connections and unstable PLL behavior.
Treat the 160 MHz clock output as a high-speed signal even though the ICS503M is only a clock generator. Use short traces, a continuous reference plane, controlled impedance where appropriate, and no unnecessary stubs. Provide local output decoupling and consider a dedicated clock buffer when the load or fanout exceeds the verified output-drive capability, which was not included in the supplied extraction.
Do not assume that every LOCO family member is a drop-in replacement for ICS503M. Frequency rating, reference range, enable logic, output configuration, supply voltage, and pin assignment can differ across the family. The provided cross-reference search identified no confirmed drop-in substitute, so compare the official datasheets and validate the replacement across startup, lock, jitter, and load conditions before production use.
Budget the clock-generator supply and PLL loop-filter network using the manufacturer's application information. The exact supply voltage, supply-current limits, decoupling values, and loop-filter equations were not present in the verified extraction. Avoid deriving those values from generic assumptions; obtain the complete datasheet because incorrect bias or filtering can impair PLL lock and introduce phase noise into the 160 MHz output.
Thông tin tuân thủ
The supplied verified records do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is treated as not applicable because ICS503M is described only as a general clock generator IC and no automotive qualification is documented.
