The SoC supports open source middleware such as RDK and prplWare. It’s designed to be used in combination with the BCM67142 or BCM67192 WiFi 8 chips for Residential Fiber-to-the-Home (FTTH) access points, multi-gigabit fiber CPEs, and 10G PON Wi-Fi Ethernet gateways.
Public documentation is fairly limited for all three chips, as Broadcom only provides product briefs through the respective product pages. and nothing else.
Broadcom says it is currently sampling the BCM68565, BCM67142, and BCM67192 chips to early access customers and partners. A few more details may also be found in the press release.
