MK2059-01SI - 25.92MHz Clock Translator | Renesas | Telecom
Артикул: MK2059-01SI ✗ Снят с производстваMK2059-01SI Обзор
A voltage-controlled crystal oscillator-based clock translator is a clock-generation IC that combines frequency translation, phase locking, and reference synchronization. It belongs to the broader clock and timing IC hierarchy, where clock generators and phase-locked loops support communication networks, digital transport systems, and other equipment requiring stable, traceable timing references. Unlike a free-running oscillator, the MK2059-01SI derives its output from an external reference, improving synchronization across a telecommunications system.
Key features include a 25.92 MHz maximum output frequency, an input-to-output ratio of 2:1, LVCMOS input and output signaling, and an integrated PLL. The supply-voltage range is 3.15 V to 3.45 V, while the rated operating-temperature range is -40°C to +85°C. The surface-mount 20-SOIC package provides a compact option for communication and timing equipment.
Internally, the device uses a VCXO-based architecture and PLL-based clock generation to lock the generated clock to the 8 kHz input reference. This phase-locked relationship is the principal technical feature: the output is not intended as an unrelated free-running oscillator but as a translated reference derived from the incoming frame clock. The PLL feature and LVCMOS interfaces place the device in the class of integrated frequency translators intended for telecommunications clocking.
Typical applications include telecommunications line equipment, frame-clock synchronization networks, clock distribution subsystems, and communication interfaces that require a derived reference from an 8 kHz source. The 25.92 MHz maximum output makes it suitable for systems operating at the stated common telecommunications reference frequency, while the 3.15 V to 3.45 V supply range supports low-voltage digital clock architectures.
Designers should verify the input reference amplitude, output waveform, PLL loop stability, and decoupling requirements against the manufacturer datasheet before layout. The LVCMOS clock path requires short, controlled-impedance routing and clean return paths, while the 20-SOIC footprint requires adequate board area and thermal consideration for reliable assembly.
This page combines verified manufacturer and distributor information with explicit data gaps, application guidance, and package-specific replacement analysis. It is intended to help engineers evaluate the MK2059-01SI without mistaking packaging variants for functionally different devices or assuming unreported electrical specifications.

Типичное применение
MK2059-01SI подходит для 6 применениеs: Telecommunications Frame-Clock Generation, Synchronous Communication Line Equipment, Clock Distribution Subsystems, Network Synchronization Modules, Frame-Referenced Digital Equipment, Industrial Telecommunication Control.
Telecommunications Frame-Clock Generation
The MK2059-01SI fits telecommunications frame-clock generation because it produces a clock of up to 25.92 MHz that is phase-locked to an 8 kHz frame-rate reference. Its 2:1 input-to-output ratio, LVCMOS interface, and PLL architecture make it suitable for deriving a synchronized clock from an existing system reference. The 3.15 V to 3.45 V supply range matches low-voltage communication logic. Before deployment, verify reference amplitude, jitter, pull range, and loop stability against the complete manufacturer datasheet.
Рекомендуется
Synchronous Communication Line Equipment
The MK2059-01SI is appropriate for synchronous communication equipment that requires a derived reference rather than an independent oscillator. Locking the 25.92 MHz maximum output to an 8 kHz input allows multiple line-card functions to share a common timing source. LVCMOS input and output simplify interface with compatible digital logic, while the PLL supports phase-controlled generation. System designers should still reserve adequate filtering and routing margin for clock edges, because the supplied data does not quantify output jitter.
Рекомендуется
Clock Distribution Subsystems
The MK2059-01SI can serve as the reference-derived source within a clock distribution subsystem where the system must preserve phase relationship to an 8 kHz frame clock. Its maximum 25.92 MHz output provides a defined upper operating point, and the LVCMOS output permits direct connection to suitable clock receivers. The design benefit is traceability to the common reference rather than independent drift. Controlled-impedance routing, short clock paths, and separate return paths are necessary to avoid degrading edge quality.
Рекомендуется
Network Synchronization Modules
The MK2059-01SI fits network synchronization modules that accept a low-frequency frame reference and require a higher clock derived from it. Phase-locking the output to the 8 kHz reference supports coherent transfer and shared timing across module boundaries. Its single-circuit implementation reduces the need for separate oscillator and divider functions. The design must meet the narrow 3.15 V to 3.45 V supply requirement and should verify the PLL behavior against the manufacturer application information before production release.
Рекомендуется
Frame-Referenced Digital Equipment
The MK2059-01SI is useful in frame-referenced digital equipment where the internal clock must remain related to a system-wide 8 kHz timing input. Its 25.92 MHz maximum output, PLL, and LVCMOS interfaces suit digital clocking blocks, while the 20-SOIC package allows integration into compact communication hardware. Using a reference-derived clock can simplify synchronization between board-level functions. Engineers should account for propagation delay, clock loading, and output waveform limits because those detailed specifications were not present in the supplied search data.
Рекомендуется
Industrial Telecommunication Control
The MK2059-01SI's -40°C to +85°C operating range supports industrial telecommunication equipment operating across extended environmental conditions. The synchronized output can coordinate clock domains that are already disciplined by an 8 kHz frame reference, while the 3.3 V-class supply reduces power-supply complexity. Its 20-SOIC package is straightforward for conventional surface-mount assembly. Production engineers should validate startup, reference stability, and clock accuracy over temperature because those parameters are not quantified in the verified distributor snippets.

Ключевые отличия
- Reference-derived 25.92 MHz clock generation (против General-purpose clock generators such as ICS501M)
- Purpose-built telecommunications frame-clock function (против ICS502M)
- Narrow 3.3 V-class operating range (против Legacy-compatible alternatives with wider supply tolerance)
Заметки по проектированию
Route the 8 kHz reference and generated clock as controlled-impedance traces with short paths and continuous ground references. Although the available data confirms LVCMOS signaling and a maximum output frequency of 25.92 MHz, it does not specify edge rates or permitted loading. Avoid long stubs, test-point discontinuities, and shared return paths that could introduce edge degradation. Place decoupling close to the supply pins after confirming the manufacturer's recommended values and capacitor type.
Design the supply rail for the specified 3.15 V to 3.45 V operating range and do not assume conventional 5 V tolerance. A stable 3.3 V-class source is indicated by the verified specifications, but allowable ripple and sequencing requirements were not included in the supplied data. Review the official datasheet power-application circuit before selecting bulk capacitance, and keep the clock generator's supply return close to the device ground connections.
Do not treat MK2059-01SI, MK2059-01SITR, MK2059-01SILFTR, and MK2059-01SILF as having identical procurement or environmental conditions merely because they use the same 20-SOIC footprint. The supplied comparison reports RoHS and lead-free differences between the legacy SI and the compliant variants. Verify the exact ordering code, assembly form, current lifecycle state, and manufacturer documentation before approving a substitution.
Clock quality depends on the reference and loop configuration in addition to the nominal 25.92 MHz maximum output frequency. The supplied data does not provide jitter, pull range, reference sensitivity, or output-drive specifications, so these values must be obtained from the Renesas manufacturer datasheet. Compare those specifications against the receiver's timing budget and perform end-to-end testing with the intended 8 kHz reference.
