The MAX8566 high-efficiency switching regulator delivers up to 10A load current at output voltages from 0.6V to (0.87 x VIN). The IC operates from 2.3V to 3.6V input supplies, making it ideal for point-of-load applications. The total output-voltage set error is less than ±1% over load, line, and temperature.The MAX8566 operates in pulse-width-modulation (PWM) mode with a 250kHz to 2.4MHz switching frequency range that is programmable by an external resistor. The IC can be synchronized to an external clock in the same frequency range using the SYNC input. The high operating frequency minimizes the size of external components. Using low-RDS(ON) n-channel MOSFETs for both high- and low-side switches maintains high efficiency at both heavy-load and high-switching frequencies.The MAX8566 employs a voltage-mode control architecture with a high-bandwidth (> 10MHz) error amplifier. The voltage-mode control architecture makes switching frequencies greater than 1MHz possible, achieving all-ceramic-capacitor designs to minimize PC board space. The error amplifier works with Type 3 compensation to fully utilize the bandwidth of the high-frequency switching to obtain fast transient response. Adjustable soft-start time provides flexibility to minimize input startup inrush current. An open-drain, power-good (PWRGD) signal goes high when the output reaches 90% of its regulation point.The MAX8566 provides a SYNCOUT output to synchronize a second MAX8566 or a second regulator switching 180° out-of-phase with the first to reduce the input ripple current, which consequently reduces the input-capacitance requirements. The MAX8566 also provides an external reference input (REFIN) for output-tracking applications.The MAX8566 is available in a 32-pin, 5mm x 5mm TQFN package. The MAX8566 and all the required external components fit into a footprint of less than 0.80in².ApplicationsASIC/CPU/DSP Core VoltagesBase-Station Power SuppliesDDR Power SuppliesFiber Power SuppliesNetwork-Power SuppliesPOL Power SuppliesTelecom Power Supplies

Integrated directdigital frequency synthesizers allow positioning of the QAMchannels with a resolution of 125Hz. The interpolation filtersand resamplers provide linear phase and excellent gain flatness.Output data from the last modulator is fed to a digital-predistortion(DPD) block that can be used to correct distortionin the device’s integrated RF-DAC and output amplifiersexternal to the device.ApplicationsEdge QAM, CMTS, CCAP, IP-QAMMulti-Dweller Unit Mini-HeadendsRemote PHY, Coax Media Converters

The MAX9271 compact serializer is designed to drive 50Ω coax or 100Ω shielded twisted-pair (STP) cable. The device pairs with the MAX9272 deserializer. The parallel input is programmable for single or double input. Double input allows higher pixel clock input frequency by registering two pixels of typical image-sensor video data before serializing. This doubles the maximum pixel clock frequency compared to single input. The device features an embedded control channel that operates at 9.6kbps to 1Mbps in UART and mixed UART/I²C modes, and up to 400kbps in I²C mode. Using the control channel, a microcontroller (µC) is capable of programming serializer, deserializer, and camera (or any peripheral) registers at any time, independent of video timing. There is one dedicated GPIO, four optional GPIOs, and a GPO output, allowing remote power-up of a camera module, camera frame synchronization, and other uses. Error-detection and correction coding are programmable. For driving longer cables, the device has programmable pre/deemphasis. Programmable spread spectrum is available on the serial output.
