MK2712SLFTR - NTSC/PAL Clock Source | Renesas | 35.469MHz
MPN: MK2712SLFTR ✓ فعالMK2712SLFTR جائزہ
A video clock synthesizer is a clock-and-timing integrated circuit that generates or organizes timing signals required by video systems. Within the product hierarchy, a video clock synthesizer is a specialized clock generator, which belongs to clock and timing ICs, integrated circuits, and semiconductors. Its PLL architecture supports frequency generation or conditioning, while the CMOS output provides a logic-compatible clock signal for downstream counters, timing circuits, and video-processing stages.
The MK2712SLFTR provides one clock circuit, a maximum listed frequency of 35.469 MHz, PLL support, clock input, and CMOS output. These characteristics distinguish it from general-purpose fixed-frequency oscillators and make it applicable where NTSC or PAL video timing is required. The single-circuit architecture also keeps the device focused on a compact legacy-video timing function rather than a multi-output modern clock-tree role.
The 8-SOIC package measures 0.154 inches wide, corresponding to a 3.90 mm package width, and is identified by the LFTR ordering code. Its eight pins provide the physical interface for power, ground, clock input, control, and generated timing signals. Exact pin names, voltage ratings, operating-temperature limits, and timing tolerances should be taken from the manufacturer pin-description table when assigning PCB nets or evaluating signal timing margins.
Typical MK2712SLFTR applications include NTSC and PAL video timing generation, analog video processing equipment, broadcast-related clocking, and legacy video test systems. In each case, the device can establish the foundational timing reference used by downstream synchronization logic. Its single clock circuit suits systems that require a dedicated video-standard clock without a larger multi-channel timing architecture.
Designers should verify output frequency tolerance, input-reference requirements, PLL lock behavior, and logic thresholds against the manufacturer datasheet before layout is released. Decoupling and signal-routing practices should follow the reference circuit associated with the selected device, while unused inputs require the prescribed bias states. Because timing specifications are sensitive to trace loading and supply integrity, short clock routes and a stable local supply connection are important.
This page combines the verified device identity, package and clock-source characteristics with a drop-in comparison, application guidance, and practical design considerations. It is intended to help engineers identify the correct legacy video timing device, confirm package compatibility, and plan a clock-source implementation without relying on generic oscillator-selection guidance.

MK2712SLFTR کے لیے موزوں ہے 6 ایپلیکیشنs: NTSC Video Timing Generation, PAL Video Timing Generation, Analog Video Processing Equipment, Broadcast Video Test Systems, Legacy Video Synchronization Circuits, Video Timing Reference Modules.
NTSC Video Timing Generation
The MK2712SLFTR is appropriate for NTSC timing because the manufacturer identifies it specifically as an NTSC/PAL clock source with PLL support. Its single CMOS clock circuit can establish the fundamental video timing reference used by counters and synchronization stages. The 35.469 MHz maximum listed frequency provides a clear upper boundary for frequency planning. Before implementation, confirm the required reference frequency, output jitter, supply voltage, and PLL lock behavior in the manufacturer datasheet.

PAL Video Timing Generation
The MK2712SLFTR supports PAL timing applications through its dedicated NTSC/PAL clock-source architecture and PLL capability. It can supply a CMOS clock reference for legacy video-processing chains that synchronize counters, blanking-related logic, or downstream display timing. The 8-SOIC package keeps the implementation compact, while the one-circuit configuration avoids the complexity of a multi-output clock generator. Validate all frequency, timing, and voltage requirements against the official datasheet.

Analog Video Processing Equipment
Legacy analog video processors often require a stable color-standard timing reference before signal processing and display synchronization can occur. The MK2712SLFTR provides an NTSC/PAL clock source with one CMOS output circuit and PLL support, allowing it to sit near the timing-control section of the board. Its maximum frequency of 35.469 MHz defines the usable clock range. Confirm input-reference conditions and timing margins before routing critical clock traces.

Broadcast Video Test Systems
A dedicated NTSC/PAL clock source can simplify legacy broadcast test equipment that must reproduce standard video timing. The MK2712SLFTR combines PLL support, a 35.469 MHz maximum frequency, and a CMOS output in an 8-SOIC package, making it suitable for timing-generation portions of a test system. Its single-circuit architecture is preferable where multi-channel clock distribution is unnecessary. Verify output accuracy, acquisition behavior, and supply requirements during hardware bring-up.

Legacy Video Synchronization Circuits
The MK2712SLFTR can provide the reference clock for legacy synchronization circuits that coordinate video timing across counters, control logic, and downstream processing blocks. Its CMOS output and PLL capability support clock generation, while the dedicated 8-SOIC package limits board area. Because synchronization errors can propagate through the video chain, preserve short clock routing, maintain a stable local supply, and verify acquisition time against the system's timing budget.
تجویز کردہ
Video Timing Reference Modules
The MK2712SLFTR fits compact reference modules designed to distribute NTSC or PAL timing to several legacy video functions. Its one-clock-circuit configuration keeps the source focused, and the 8-SOIC package supports surface-mount integration without a large through-hole footprint. The 35.469 MHz maximum frequency and CMOS output provide the principal planning constraints. Confirm power consumption, startup behavior, and clock-output load capability before final module design.

ڈیزائن نوٹس
Assign the clock input and clock output nets from the manufacturer pin-description table before routing. Keep the clock output trace short, avoid unnecessary stubs and test pads, and route it away from switching nodes and high-current edges. For an 8-SOIC implementation, confirm the physical pin-one orientation and land pattern during library construction rather than relying only on the generic SOIC-8 footprint.
Use the supply range, bypass recommendations, and decoupling values from the manufacturer application circuit. Place the local decoupling capacitor close to the supply and ground pins and minimize the supply-loop area. PLL-based clock sources can be sensitive to supply disturbance, so keep the analog or clock-reference section physically separated from switching-converter paths where the board layout permits.
Do not assume that a shared SOIC-8 footprint guarantees complete electrical equivalence. The identified MK2761ASLFTR replacement has consistent terminals and main functional characteristics according to the component comparison, but voltage range, temperature limits, jitter, PLL lock behavior, and frequency accuracy still require comparison. Recheck every unused input state and startup condition before approving a drop-in substitution.
