The XR77103-MoCA PMIC is designed to power MaxLinear’s G.hn chipsets, the MoCA 2.0 MxL370x and MoCA 2.5 MxL371x along with a single port Ethernet PHY such as the GPY241. It features 3 high efficiency synchronous buck regulators with integrated power switches and sequencing engine to provide the 0.9V, 1.8V, and 3.3V rails of the MoCA SoC. The 0.9V core rail is capable of supplying the 3A peaks demanded by the SoC(1) and is compatible with the SoC DVS control.
 
The XR77103-MoCA can operate from 5V, 9V, and 12V powered systems with minimal required external components, and packaged in a 4x4mm QGN that provides the smallest size solution possible. With a nominal switching frequency of 560kHz, the regulators can also be synchronized to an external clock in applications where EMI control is critical. An internal supervisor circuit monitors each converter output and asserts PGOOD once sequencing is done, outputs are reported in regulation, and the reset timer expires.

XR77103-MoCA features a supervisor circuit that monitors each converter output. The PGOOD pin is asserted once sequencing is done, outputs are reported in regulation, and the reset timer expires. The polarity of the signal is active high.

Distribution Date Description File
07/17/2023 In 2023, MaxLinear will be converting all shipping labels for the parts noted from an EXAR format to MaxLinear’s label. During this transition customers may receive either label. This change affects only shipping and packing labels. This change will not affect the part number, part marking, manufacturing process or manufacturing sites. Only work in progress material will be converted. Existing inventory from MaxLinear’s warehouse, channel sales, distributor, and such, will not be converted. Hence, customers may experience receiving mixed shipments with both Exar and MaxLinear labels for some period until existing inventory of old labels is eventually cleared out. Situation is product to product with no predictable way to determine when all old labels will be exhausted. No change to product form, fit, function and reliability. ADDENDUM A: Fixed MBB label logo for DX204001 to MaxLinear logo. ADDENDUM B: Replaced ‘All other affected products outer box label’ with clearer pictures. Corrected Date Issued (from original PCN) issue date +90 days to August 30, 2023.
