What are the key features of PLMK00804BQWRGTTQ1?
- 1-to-4 low-skew fan-out distributes a single clock to 4 LVCMOS outputs simultaneously, minimizing clock tree skew across board designs
- Differential MUX input conditioning accepts LVPECL, LVDS, or LVCMOS clock sources, eliminating the need for external AC-coupling or termination networks
- 1.5 V to 3.3 V supply range enables direct level translation between mixed-voltage clock domains in a single device
- 16-pin QFN package occupies minimal PCB area while providing thermal pad for reliable operation in temperature-sensitive automotive and industrial systems
What is PLMK00804BQWRGTTQ1 used for?
The PLMK00804BQWRGTTQ1 is designed for high-performance clock distribution in FPGAs, ASICs, and multi-processor SoC systems where a single reference clock must be fanned out to 4 low-skew LVCMOS endpoints with matched propagation delays. Communications equipment and test instrumentation benefit from its differential input MUX, which allows seamless switching between a primary and secondary clock source without glitches. Automotive infotainment and ADAS platforms leverage its 1.5V to 3.3V supply flexibility to bridge clock signals across mixed-voltage subsystems in a compact 16-pin QFN footprint.

Frequently Asked Questions
How many output channels does the PLMK00804BQWRGTTQ1 drive simultaneously and at what voltage levels?
The PLMK00804BQWRGTTQ1 drives 4 LVCMOS output channels simultaneously. Each output swings between GND and the supply voltage, which can be set anywhere from 1.5 V to 3.3 V, enabling direct interfacing to 1.8 V or 2.5 V logic families without additional level-shift buffers.
What clock input formats does the differential MUX on the PLMK00804BQWRGTTQ1 accept?
The differential MUX input conditioning accepts LVPECL, LVDS, HCSL, and LVCMOS clock sources. This versatility lets designers connect the device directly to oscillators or PLL outputs operating at differential signaling standards without external AC-coupling capacitors, reducing BOM cost and board space.
Which automotive or industrial designs benefit from the PLMK00804BQWRGTTQ1 AEC-Q100 qualification?
ADAS camera serializer boards, radar front-end modules, and V2X communication units that distribute a 100 MHz to 300 MHz reference clock to multiple processing cores benefit most. The AEC-Q100 qualification ensures reliable operation across the automotive temperature range of -40°C to 125°C, which is required for under-hood electronic modules.
How does output skew affect timing margins when using the PLMK00804BQWRGTTQ1 in multi-FPGA designs?
The low-skew fan-out buffer keeps output-to-output skew below 50 ps typically, which preserves timing margins in multi-FPGA clock trees running at 200 MHz or faster. Tight skew means all 4 receiving devices capture data on the same clock edge, eliminating metastability hazards in synchronous cross-FPGA data transfers.
