MK2746G - 133.33MHz Clock Synthesizer | Renesas | DVD

DVD Player Clocking

The MK2746G is a strong fit for DVD-player timing because the verified DigiKey listing identifies it as a one-channel clock and frequency synthesizer rated at 133.33 MHz, while the available family documentation specifically targets DVD systems. It can serve the central timing reference derived from a 27 MHz crystal or clock input, reducing dependence on a broad-purpose programmable clock generator when only the required DVD frequencies are needed. The main design benefit is purpose-specific integration in a compact 16-pin TSSOP package. Before selecting it, engineers must confirm the exact output configuration, allowable jitter, lock time, supply voltage, output capacitance, and direct PCB compatibility with the target DVD design. Those electrical details are not present in the supplied snippets and must come from the official Renesas datasheet.

MPEG2 Media Processor Timing

The MK2746G is suitable as a dedicated timing source for MPEG2-based media electronics because its stated application class includes MPEG2 systems and its verified maximum listed frequency is 133.33 MHz. A stable reference derived from the specified 27 MHz crystal or clock input can organize a processor, memory interface, video pipeline, or digital audio subsystem around a known clock relationship. Using a purpose-built synthesizer may simplify a fixed DVD or MPEG2 design compared with a configurable generator. The critical tradeoff is integration: verify whether every required clock output is present, whether unused outputs need termination, and whether the analog PLL's lock and jitter performance satisfy the media pipeline. Because those details are unavailable in the verified snippets, they remain mandatory pre-layout checks.

Consumer DVD Set-Top Equipment

In consumer DVD set-top equipment, the MK2746G can provide a dedicated clock function where the architecture is built around a 27 MHz reference and a 133.33 MHz-class requirement. Its 16-pin TSSOP package is compatible with surface-mount assembly, and its single-channel identity makes the role straightforward when only one principal synthesized clock domain is required. Compared with a universal clock generator, the device may reduce configuration overhead for a fixed multimedia product. Designers should still check startup sequencing, crystal loading, PLL lock indicators if any, output termination, decoupling, and electromagnetic-emission behavior. Verify the current package drawing and production recommendations in the Renesas documentation because the supplied search results do not expose those implementation details.

MPEG2 Video Timing Reference

The MK2746G can support an MPEG2 video subsystem that requires a predictable 133.33 MHz-class timing reference. The device's verified one-channel synthesizer role and documented low-jitter orientation make it relevant where a stable relationship between a 27 MHz source and downstream digital logic is essential. The analog PLL approach may reduce the number of unrelated clock domains when the complete design is planned around MK2746 outputs. However, video quality can depend on synchronization margin even when nominal frequency is correct, so engineers must verify peak-to-peak or RMS jitter, phase noise, long-term frequency stability, and clock-cycle requirements from the complete datasheet. The supplied evidence supports application selection but not final timing sign-off.

Digital Audio and Video System Integration

The MK2746G can be evaluated for integrated digital audio and video equipment that combines DVD or MPEG2 processing with a 27 MHz reference and a 133.33 MHz-class clock requirement. A dedicated synthesizer can provide a consistent timing reference across processing and interface blocks while retaining a relatively compact 16-pin TSSOP footprint. The engineering benefit depends on whether the required clock tree is fixed; if multiple independently programmable outputs or different standards must be supported simultaneously, a multi-channel generator may be more appropriate. Validate supply tolerance, output drive, load capacitance, clock-tree fanout, and sequencing before selecting MK2746G. These parameters are not quantified in the verified web material and must not be inferred.

Fixed-Function Multimedia System Reference Clock

The MK2746G is appropriate for a fixed-function multimedia architecture that prioritizes a dedicated low-cost, low-jitter clock synthesizer over general-purpose frequency synthesis. The verified 133.33 MHz listing and 27 MHz input description support its use as a reference-generating element rather than a complete system clock-tree solution. Designers should define downstream loading and distribution first, then confirm that the MK2746 output can drive the intended network without excessive loading. PCB placement should minimize sensitive-node capacitance and provide a clean return path, while power and ground pins should follow the manufacturer layout guidance exactly. Because the supplied sources do not expose the full pinout or electrical limits, layout release should wait for direct review of the current Renesas MK2746 datasheet.
