MK2308S-1H - 133MHz 8-Output Zero-Delay Buffer | Renesas
MPN: MK2308S-1H ✗ Cuối đờiMK2308S-1H Tóm tắt
A zero-delay buffer is a clock and timing IC that regenerates a reference clock through a phase-locked loop, compensating for clock-distribution delay while preserving frequency. In the hierarchy of electronic components, this device belongs to clock and timing integrated circuits, then PLL-based clock drivers, frequency-distribution circuits, and finally broader digital and power-management systems. It is used where multiple logic domains need closely related clock signals.
Key verified features include a maximum clock frequency of 133 MHz, eight low-skew outputs, CMOS-compatible signaling, 3.0 V to 3.6 V operation, and selectable tri-state or stop-at-a-low output behavior. The PLL can be bypassed for testing or direct clock propagation. The available operating-temperature information identifies a 0°C to 70°C range, making the device suitable for commercial-temperature clock-distribution equipment.
The low-skew output architecture helps maintain timing relationships across multiple destinations, which is important in networking, telecommunications, and computing systems. Its 3.3 V supply operation is compatible with systems designed around modern CMOS clock domains, while the SOIC package supports conventional surface-mount assembly and inspection.
Typical uses include clock fan-out for communications equipment, synchronized digital logic, computing interfaces, test and measurement systems, and embedded control platforms. Designers should account for trace-length matching, output-enable control, bypass testing, and the required decoupling capacitors. The verified datasheet search result specifically calls for 0.01 uF capacitors near the device power pins.
This page combines verified distributor and manufacturer information, cross-reference results, application guidance, and design considerations into an engineering-focused component record. It is intended to support purchasing decisions while clearly separating verified values from parameters requiring further datasheet confirmation.

Ứng dụng tiêu biểu
MK2308S-1H phù hợp cho 6 Áp dụngs: Networking Clock Distribution, Telecommunications Clock Fan-Out, Digital Computing Systems, Test and Measurement Equipment, Embedded Control Platforms, Industrial Digital Control.
Networking Clock Distribution
The MK2308S-1H fits networking equipment that must distribute one input clock to several logic or interface domains while maintaining controlled skew. Its verified 133 MHz maximum frequency and eight CMOS outputs provide useful fan-out for communications systems. Place the device near the clock source, route outputs with matched impedance, and use the PLL mode when regenerated low-skew clocks are required. The 3.0 V to 3.6 V supply range aligns with 3.3 V CMOS systems, while the 200 ps skew figure provides a concrete timing target for system-level budgeting.

Telecommunications Clock Fan-Out
Use MK2308S-1H when telecommunications logic needs several related clocks at up to 133 MHz. The eight-output architecture reduces the number of separate clock buffers, and PLL-based operation supports zero-delay distribution where the system timing budget is tight. The direct-input bypass path is useful during production test or diagnostic operation. Designers should preserve short return paths, provide local 0.01 uF decoupling near the specified supply pins, and verify control timing for tri-state and stop-at-a-low modes.
Được đề xuất
Digital Computing Systems
The MK2308S-1H is suitable for computing systems that distribute a common reference clock to processors, memory controllers, or high-speed interface blocks. Its eight outputs can support several destinations, while the verified 133 MHz ceiling defines the intended operating class. Select PLL operation for regenerated timing and bypass operation when direct testing is more useful. The SOIC-16 package supports conventional surface-mount assembly, but package-level performance still depends on controlled impedance, output loading, and careful power-ground routing.
Được đề xuất
Test and Measurement Equipment
MK2308S-1H can serve as a clock source and fan-out element in test and measurement systems where multiple CMOS loads need a common reference. The direct-input path provides a way to test signal behavior without relying exclusively on PLL regeneration, while eight outputs allow several instruments or DUT interfaces to be driven from one device. Keep output rise and fall times, load capacitance, and trace length within the device's verified operating envelope. Confirm jitter, skew, and temperature requirements from the complete manufacturer datasheet before using it as a precision reference.
Được đề xuất
Embedded Control Platforms
The MK2308S-1H can distribute a reference clock among embedded processors, serial links, and peripheral blocks requiring related CMOS timing. It is most appropriate when the system operates within the verified 3.0 V to 3.6 V range and does not exceed 133 MHz. The PLL and bypass choices allow normal operation and test access, but enable polarity and tri-state behavior must be checked in the exact device revision. Use short, impedance-controlled traces and verify that all destinations tolerate the output load and clock phase relationship.
Được đề xuất
Industrial Digital Control
For industrial digital-control equipment, MK2308S-1H provides a compact way to fan a 133 MHz-class reference clock into multiple logic sections. The 0°C to 70°C verified temperature range supports commercial-temperature systems, but industrial requirements beyond that range require separate qualification. Pay particular attention to ground-plane continuity and clock-output isolation when motors, power converters, or long cables share the board. The 200 ps skew value gives designers a useful starting point for checking downstream timing margins.

Ghi chú thiết kế
Place the required 0.01 uF decoupling capacitors between VDD and GND as close as possible to the supply pins identified in the verified datasheet search result. Keep the VDD path short, use a low-impedance ground return, and avoid routing sensitive clock inputs beside switching or high-current return paths. The 3.0 V to 3.6 V supply range must be maintained at the device pins under transient load, not only at the source.
Treat all eight outputs as high-speed clock nets. Use short, impedance-controlled routes and account for destination capacitance, connector loading, and trace-length differences before claiming the 200 ps skew target is achieved. PLL mode and direct-input bypass mode should be validated separately because their timing behavior is not interchangeable. Probe or simulation should confirm rise time, ringing, and clock phase at the worst-case load.
Keep the input, outputs, supply, and ground connections compact and separate noisy power paths from clock distribution. The SOIC-16 package is small enough that pin escape routing can introduce unequal delays, especially when outputs fan out to widely separated destinations. Match trace geometry where practical, provide a continuous ground plane, and place test points that do not add excessive loading. Verify the exact pinout from the manufacturer datasheet before fabrication.
Thông tin tuân thủ
The supplied verified results do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for MK2308S-1H. A related third-party MK2308 listing reports halogen-free compliance, but that information was not treated as verified for the target MPN.
