MAX9150EUI+ 概要
An LVDS repeater is a signal buffer and redriver that accepts a single high-speed differential input and regenerates multiple identical differential outputs. In the signal-integrity hierarchy, it sits between an LVDS driver and its receivers, restoring degraded edge rates and isolating downstream loading from the source. Repeaters are essential in high-speed clock and data distribution trees where fan-out, trace length, or connector discontinuities would otherwise corrupt a direct LVDS link.
Key features of the MAX9150EUI+ include ultra-low 120ps p-p maximum total jitter, guaranteed 100ps maximum skew between channels, and a 400Mbps guaranteed data rate that comfortably supports clock distribution up to 200MHz. A shutdown mode draws only 60uA of supply current, enabling aggressive power management in battery-operated and power-sensitive systems. The device conforms to the EIA/TIA-644 LVDS standard, ensuring interoperability with standard LVDS transmitters and receivers.
Technically, the device accepts a single LVDS input pair and fans it out to ten LVDS output pairs. Low-voltage differential signaling uses a ~350mV current-mode differential swing across a 100-ohm terminated line, which inherently minimizes EMI, crosstalk, and power compared with single-ended signaling such as LVTTL. The repeater's low deterministic and random jitter budget preserves timing margin across the full 10-way fan-out, which is critical in clock-tree design where each output contributes skew to the timing budget.
Typical applications include backplane clock and data distribution, point-to-point LVDS link extension with 100-ohm terminated lines, high-speed data fan-out in industrial automation, medical imaging receivers, and telecommunications line cards where a single source must drive many loads without signal degradation.
A key design consideration: terminate each LVDS output line with a 100-ohm resistor at the far end, and keep the total capacitive loading balanced across outputs to preserve the 100ps inter-channel skew specification.

主な用途
MAX9150EUI+ の用途: 6 件s: Backplane Clock Distribution, Point-to-Point LVDS Link Extension, Industrial Automation Fan-Out, Medical Imaging Signal Distribution, Telecommunications Line Cards, High-Speed Data Fan-Out in Test Equipment.
Backplane Clock Distribution
In modular industrial and telecom backplanes, a single central clock must reach every slot without degradation. The MAX9150EUI+ accepts one LVDS clock input and regenerates ten LVDS output pairs with a guaranteed 400Mbps rate, 120ps p-p total jitter, and only 100ps maximum inter-channel skew, so all ten slots receive essentially simultaneous clock edges. Its EIA/TIA-644 compliance guarantees interoperability with standard LVDS PLLs and FPGA clock inputs, and its low-power differential signaling minimizes EMI across the backplane. Length-match output traces and terminate each pair with 100 ohms at the receiving end to preserve the skew budget.
おすすめ
Point-to-Point LVDS Link Extension
Long LVDS runs across cables, connectors, and backplanes accumulate jitter and attenuate edges beyond what a receiver can tolerate. Placing the MAX9150EUI+ mid-link redrivers the signal: the input stage re-slices the degraded waveform and the output stage launches a fresh ~350mV LVDS swing into the next 100-ohm terminated segment. With 120ps p-p maximum total jitter and 400Mbps guaranteed throughput, each repeater stage adds well-understood timing cost, letting designers cascade segments with calculable margin. The 60uA shutdown current also lets unused links be power-gated via system firmware.
おすすめ
Industrial Automation Fan-Out
PLCs, motion controllers, and vision systems distribute encoder counts, trigger pulses, and reference clocks to many axes simultaneously. The MAX9150EUI+ fans a single LVDS trigger or clock to ten axis modules with 100ps maximum inter-channel skew, which directly reduces the uncertainty between synchronized motion axes. Its -40C to +85C industrial temperature rating matches factory floor ambient conditions, and differential signaling rejects the high motor-drive noise typical of these cabinets. The 28-pin TSSOP conserves PCB area inside dense I/O cards compared with discrete fan-out buffers.
おすすめ
Medical Imaging Signal Distribution
Ultrasound, CT, and digital X-ray front ends distribute sampling clocks from one low-phase-noise source to many analog-front-end chips. The MAX9150EUI+'s 120ps p-p total jitter limit keeps clock tree noise from converting into aperture jitter at the ADCs, protecting spurious-free dynamic range, while 100ps channel skew preserves simultaneous sampling alignment across channels. Operating at 3.0V to 3.6V from a clean analog rail with 0.1uF local decoupling, the device integrates into noise-sensitive imaging boards without adding switching noise, unlike a clock-multiplying PLL solution.
おすすめ
Telecommunications Line Cards
Telecom shelf architectures distribute a system reference clock from a central timing card to every line card. The MAX9150EUI+ repeats the incoming LVDS reference and delivers ten disciplined outputs with 100ps maximum skew, supporting SONET/SDH-style timing distribution where skew between cards must stay inside synchronizer capture windows. Conformance to EIA/TIA-644 ensures clean integration with standard LVDS PHYs and FPGAs on the line card. The 160mA active supply current is acceptable on line-card power budgets, and 60uA shutdown supports standby power compliance.
おすすめ
High-Speed Data Fan-Out in Test Equipment
Bench instruments, logic analyzers, and automated test equipment often need one fast trigger or sample clock routed to many measurement channels without skew-induced timing error. The MAX9150EUI+ provides a deterministic 100ps maximum inter-channel skew at 400Mbps, so channel-to-channel timing alignment is known and calibratable. Its 28-pin TSSOP footprint fits dense probe-front-end boards, and the EIA/TIA-644-compliant outputs drive 100-ohm terminated coax-to-board transitions cleanly. Length-match the ten output pairs and keep stubs under 5mm to hold the datasheet skew figure at the connectors.

設計ノート
Terminate every LVDS output transmission line with a 100-ohm resistor at the far (receiver) end, as required by the EIA/TIA-644 standard. Unguarded stubs longer than about 5mm cause reflections that consume the 120ps jitter budget. Length-match the ten output pairs to each other (target skew < 25ps from PCB) so that the device's guaranteed 100ps inter-channel skew dominates the total, and route pairs over a continuous reference plane with a solid ground under the 28-pin TSSOP.
The MAX9150EUI+ draws up to 160mA active supply current from a 3.0V to 3.6V rail, so worst-case dissipation is about 0.58W (Estimated: 3.6V x 160mA). No heatsink is needed, but provide a low-impedance supply: a 10uF bulk capacitor plus a 0.1uF ceramic capacitor within 5mm of the VCC pin. The 60uA shutdown mode lets firmware power-gate idle links - hold the shutdown pin asserted during standby and allow one output-edge-time for wake before the first clock.
Do not leave unused output pairs unterminated on long traces - tie them off or leave short and unterminated near the device to avoid radiating reflections. Do not substitute the commercial-grade MAX9150CUI in designs that must operate below 0C; the E suffix (-40C) is required for industrial ambient. Finally, confirm the exact pinout order of the LVDS input pair and ten output pairs from the current Analog Devices datasheet revision before finalizing the footprint - never copy footprints from legacy Maxim-era documents.
Place the MAX9150EUI+ close to the LVDS source entry connector to minimize input-pair degradation, and fan the ten outputs out symmetrically on opposite sides of the TSSOP-28 to balance trace lengths. Keep clock pairs away from switching-regulator inductors and motor-drive wiring; although LVDS is differential and noise-tolerant, the 120ps jitter specification is measured under clean conditions and additive crosstalk is not covered by the datasheet guarantee.
