MK2308S-2I Übersicht
A zero-delay buffer is a clock and timing semiconductor that uses a phase-locked loop to reproduce a clock while compensating for propagation delay introduced by the buffer. In the broader hierarchy, it belongs to clock and timing ICs, frequency-control ICs, and PLL-based clock circuits. Its purpose is to supply multiple closely related clock outputs to high-speed digital systems.
The available records identify the MK2308-2 family as a low-jitter, low-skew, PLL-based device intended for high-speed applications. The family description states that its eight outputs operate at speeds up to 133.3 MHz at 3.3 V. Four outputs are specified at one-half the input frequency, while the remaining outputs support zero-delay operation or direct clock bypass. The package is identified as a 16-SOIC measuring 3.90 mm wide.
Because the target suffix denotes a specific ordering configuration, engineers should verify temperature grade, tube packaging, and production lifecycle status against current Renesas documentation before committing a new design. The verified web results establish the core function and several headline specifications, but they do not provide a complete parameter table, guaranteed timing limits, or an official manufacturer URL for this exact suffix.
Typical uses include processor clock distribution, communications equipment, storage controllers, test systems, and other circuits requiring several outputs derived from one clock source. The divided bank can support lower-frequency peripherals while the undivided outputs serve the main digital domain. Independent output control may support testing and bus management, subject to the functions and limits stated in the datasheet.
The principal design task is to verify clock-edge integrity at the intended voltage and frequency. Board traces should be short and return-current paths continuous, while PLL input and bypass connections must follow the manufacturer layout guidance. Probe or capacitance added by test equipment can alter edge rate and skew, so timing validation should include realistic loading.
This page consolidates distributor availability, the Renesas MK2308-2 family description, package information, and replacement research. It also separates verified facts from missing production data so procurement and design teams can assess the MK2308S-2I without mistaking search snippets for a complete datasheet specification.

Typische Anwendungen
MK2308S-2I ist geeignet für 6 Anwendungs: Processor Clock Distribution, Communications Equipment, Industrial Control and Automation, Test and Measurement Systems, Network Storage and Interface Control, Synchronous Digital Logic.
Processor Clock Distribution
The MK2308S-2I fits a design needing one reference clock expanded into up to eight CMOS outputs. Its documented 133.3 MHz ceiling provides headroom for high-speed digital logic, while the four divided outputs can feed lower-rate blocks. Place the device near the clock source and load-bearing circuits to limit trace-induced skew, then validate timing at the intended 3 V or 5 V operating point using the family’s guaranteed timing tables.
Empfohlen
Communications Equipment
Communications equipment can use the MK2308S-2I to distribute a common clock through the 16-SOIC device instead of duplicating oscillators. The PLL-based architecture supports up to 133.3 MHz according to the verified family description, and the divided-output bank provides clock options without another source. Engineers should control return current, terminate unused outputs as directed, and confirm jitter and skew against each transceiver’s clock requirement.
Empfohlen
Industrial Control and Automation
The MK2308S-2I can provide related clock domains for controller, logic, and communications sections in industrial automation equipment. A single reference reduces the number of independent oscillators, while the four one-half outputs allow slower interfaces to share the source. Its 3 V to 5.5 V range suits common embedded logic levels, but the unspecified operating-temperature limits must be checked before industrial deployment.
Empfohlen
Test and Measurement Systems
Instrumentation can use the MK2308S-2I to generate multiple synchronized outputs from a common reference and preserve low-skew relationships between channels. The bypass function described for the MK2308-2 family can support testing that compares PLL behavior against a direct clock path. Because probe loads and long cable connections can distort edges, use short local routes or suitable buffers instead of driving measurement cables directly.
Empfohlen
Network Storage and Interface Control
A storage controller or high-speed interface can benefit from outputs derived from one reference because shared-frequency domains reduce independent phase drift. The MK2308S-2I supports up to 133.3 MHz and offers a divided bank, but load-dependent jitter, edge rate, and output skew must be checked in the complete data. Route each output according to rise time, and keep the PLL reference and decoupling network close to the device.
Empfohlen
Synchronous Digital Logic
The MK2308S-2I is applicable when multiple synchronous logic domains must originate from one clock, including processors, memory interfaces, and peripheral controllers. The PLL zero-delay function is intended to compensate nominal buffer propagation, while the 1/2X bank can reduce clock frequency for selected circuits. Success still depends on pin assignment, output enable state, load capacitance, and skew at the receiving device rather than only the oscillator frequency.

Designhinweise
Treat every clock output as a high-speed transmission line even when the nominal frequency is below 133.3 MHz. Route the PLL input, ground return, and bypass network exactly as specified in the Renesas family documentation, and keep output traces short enough to preserve the intended edge rate and skew. Validate with realistic receiver capacitance, probe loading, and the final multilayer stackup rather than relying only on simulation.
Place the decoupling capacitor and clock-source components close to their associated pins, with a compact ground-return path. Avoid routing clock signals across plane splits or through noisy power-regulator areas. The four divided outputs should reach only the loads that require one-half frequency, while the zero-delay outputs should be assigned according to the verified pin table and timing requirements before PCB release.
Do not infer compatibility from the MK2308 or 2308 naming alone. Suffixes can identify package, temperature, qualification, and shipping-method differences, and the verified data does not establish that any alternative has the same 16-SOIC footprint, eight output assignments, bypass behavior, and 133.3 MHz timing. Compare the manufacturer pinout, electrical tables, status, and qualification before substituting a part.
