MaxLinear Introduces PMIC to Meet the Power Needs of its SoCs


MaxLinear has announced the immediate availability of a power management integrated circuit (PMIC), the XR77103-MoCA, designed to meet the power needs of MaxLinear MxL370x MoCA 2.0 and MxL371x MoCA 2.5 SoCs.

As service providers invest in multi-gigabit broadband infrastructure, Multimedia over Coax Alliance (MoCA) solutions are needed to extend this high performance to the in-home network. Home routers and Wi-Fi extenders using MaxLinear MoCA 2.5 technology create a reliable wired backbone that can distribute multi-gigabit speeds seamlessly throughout the home or office.

With the XR77103-MoCA, a highly integrated custom power management device, supporting these chipsets, the engineering process is simplified, reducing development time, minimizing board space and ensuring quality performance.

MaxLinear is committed to providing a complete solution that ensures faster product design and a more reliable product,” said James Lougheed, Vice President, High Performance Analog products. “The MxL7310 was the world’s first fully-integrated circuit to support the multi-gigabit MoCA 2.5 standard. With the XR77103-MoCA PMIC, MaxLinear provides the same level of integration and performance to the power supply.”

The XR77103-MoCA PMIC is custom designed to provide 3 voltage rails with exact sequencing requirements for the MxL37xx SoCs and accompanying Ethernet PHY. With the addition of MaxLinear GPY211 2.5GbE PHY, the entire solution has been qualified, demonstrating world-class performance on MoCA loopback tests through a -60 dB attenuator at 2.5 GB.

The XR77103-MoCA can operate from any voltage input from 4.5 to 14 V and is offered in a 4 x 4 mm QFN package. With three highly efficient, synchronous buck regulators integrated into the device, it saves 14 external components over prior solutions reducing board space by 25 %. The three outputs are pre-set to 0.9 V, 1.8 V, and 3.3 V as the system requires with exact timing handled by the PMIC sequencing engine. The 0.9 V core rail can supply the 3 A peaks demanded by the SoC and is compatible with SoC DVS (Dynamic Voltage Scaling) to optimize performance.
