ICS501GT - 160MHz PLL Clock Generator | Renesas Electronics
料号： ICS501GT ✓ 量产中ICS501GT 概述
A clock generator IC is a timing semiconductor that converts a lower-frequency crystal or external clock into a stable, high-frequency clock required by digital systems. Clock generators occupy the Clock & Timing category and may include oscillator, PLL, frequency multiplier, divider, and buffer functions. The ICS501GT uses phase-locked-loop technology to multiply a reference frequency while providing a CMOS output suitable for digital logic and communications equipment.
Principal features include a maximum frequency of 160 MHz, one internal clock-generating circuit, support for crystal or clock inputs, and CMOS output. The 1:1 ratio indicates that the nominal output follows the selected reference relationship without an integer multiplication factor other than the internally programmed PLL ratio. The single-circuit architecture simplifies designs that require only one principal clock domain and reduces the number of separate oscillator packages and interconnections.
The ICS501GT is identified as a LOCO-family device, with LOCO standing for Low Cost Oscillator. Its PLL-based approach is intended to produce a high-quality, high-frequency clock from a lower-frequency crystal or clock source. The resulting CMOS output can serve digital processors, programmable logic, interface controllers, and other clocked subsystems, provided that the reference frequency, operating voltage, output loading, and timing requirements are checked against the device specifications.
Typical applications include communications and networking modules, industrial control equipment, consumer electronics, embedded digital systems, and FPGA or microcontroller clock trees. In these systems, the part can centralize clock generation, reduce crystal-oscillator component count, and provide a consistent clock source to multiple sequential logic domains. The exact frequency plan must remain within the 160 MHz maximum and comply with the PLL multiplication and timing limits defined by the manufacturer datasheet.
The primary design consideration is confirming the complete pin configuration and reference requirements before layout. Crystal load capacitance, grounding, output termination, supply decoupling, and unused-pin treatment all affect clock quality and reliability. Follow the manufacturer pin-description table and recommended application circuit when assigning PCB tracks, and preserve short return paths from the clock output to the load to limit susceptibility to edge degradation and crosstalk.
This product page organizes the ICS501GT clock-generator specifications, package information, documented substitution candidates, application guidance, and practical design notes into one engineering-focused reference. It supports faster part identification while highlighting the decisions engineers must still verify: frequency ratio, electrical limits, pin compatibility, lifecycle suitability, and application-specific timing requirements.

典型应用
ICS501GT 适用于 6 应用s: Communications Module Clocking, Industrial Control Systems, FPGA and Processor Clock Trees, Network Interface Equipment, Consumer Electronics Timing, Embedded Digital Control.
Communications Module Clocking
The ICS501GT is appropriate for communications modules that require a centralized CMOS clock from a crystal or external clock source. Its PLL architecture can produce a high-quality, high-frequency clock, while the documented 160 MHz maximum provides substantial timing headroom for common digital data paths. Use it where a single clock domain needs a stable source without distributing multiple independent oscillator outputs. Keep the output route short, reference the clock receiver ground correctly, and verify the selected PLL ratio against the communications controller’s permitted input range before releasing the PCB layout.
推荐
Industrial Control Systems
ICS501GT can support the timing backbone of an industrial controller by producing a CMOS clock for processors, programmable logic, and communication peripherals. The 1:1 ratio and 160 MHz maximum make it useful for designs whose reference source and required operating frequency fit the ICS501 PLL architecture. Because control systems may impose stricter environmental and lifecycle expectations, verify the operating-temperature range and qualification requirements before installation. The clock trace should be isolated from motor-control switching nodes and routed over a stable ground reference.
推荐
FPGA and Processor Clock Trees
The ICS501GT fits FPGA or processor clock trees that require a common, high-quality CMOS source from a crystal or clock input. Its PLL-based design supports frequency generation from a lower-frequency reference, and its maximum frequency of 160 MHz covers many conventional digital logic domains. Select the multiplier relationship so that the resulting clock stays within both the ICS501GT and the receiving device’s limits. Provide local decoupling and a low-impedance return path, and avoid splitting the output into long daisy-chained routes that could degrade edge quality.
推荐
Network Interface Equipment
ICS501GT is suitable for network-interface equipment requiring a centralized clock for digital datapaths, interface controllers, and status logic. The 160 MHz maximum frequency and CMOS output provide a practical timing source for equipment operating below that limit, while the single-circuit architecture simplifies designs that do not require multiple independent outputs. Route the clock according to the receiving device’s edge and load requirements, and keep the oscillator area away from power-converter and high-speed data paths. Validate jitter and reference accuracy against the interface’s timing budget before production release.
推荐
Consumer Electronics Timing
The ICS501GT can serve as the principal clock generator in consumer electronics with a processor, display interface, storage controller, or other digital subsystem. Its clock-or-crystal input supports both onboard-resonator and externally distributed reference arrangements, while the eight-pin surface-mount package simplifies board integration. The implementation should minimize the distance between the generator and timing consumers, maintain a continuous ground plane beneath the clock route, and account for the load presented by each receiver. Confirm the complete operating envelope before using the part in a temperature- or vibration-sensitive enclosure.
推荐
Embedded Digital Control
ICS501GT is applicable in embedded digital control products where a microcontroller and associated logic need a consistent CMOS timing reference. The PLL-based clock generator can replace a collection of discrete frequency-generating elements while offering a maximum operating frequency of 160 MHz and a 1:1 nominal ratio. Choose it when the system architecture requires controlled PLL-based clock generation rather than a simple fixed-frequency resonator. Follow the reference-circuit layout, maintain short clock connections, and verify startup, reference amplitude, and load requirements against the manufacturer application guidance.

设计说明
Place the ICS501GT close to the crystal or reference-clock source and to the first clock consumer. Follow the manufacturer recommended application circuit for load capacitance, grounding, and decoupling. Keep the crystal loop compact, use a continuous ground reference, and avoid routing the clock alongside switching nodes or high-speed data that can couple noise into the output.
Treat the CMOS clock output as a high-speed signal even when its frequency appears modest. Minimize branch stubs, provide a low-impedance return path, and confirm the receiver input capacitance, trace length, and target edge rate. If the clock is distributed across a board, validate edge degradation and jitter at the far endpoint rather than relying only on a measurement at the generator pin.
Do not substitute an alternative solely because its package has eight pins. Verify the pin assignments, crystal mode, supported reference frequency, supply limits, PLL ratio, output drive, and lifecycle status against the manufacturer datasheet. The documented ICS501 family comparisons establish strong substitution potential, but production approval still requires the electrical and timing details to be confirmed.
