MaxLinear and Broadcom DOCSIS 4.0 chips clear CableLabs interoperability test
DOCSIS 4.0 cable modems utilizing MaxLinear's Puma 8 and Broadcom's 'unified' chips have achieved 'verified for interoperability' approval from CableLabs. This signifies a major step in the deployment readiness of these next-generation modem chips.
Key Takeaways
- CableLabs gave MaxLinear’s Puma 8-based DOCSIS 4.0 modems “verified for interoperability” approval.
- Broadcom’s DOCSIS 4.0 “unified” chips also passed CableLabs’ interoperability test.
- The approval covers cable modems, not a broader service launch or rollout timeline.
- The source frames the certification as a major step in deployment readiness for DOCSIS 4.0 modem chips.
Why It Matters
This is a concrete validation step for DOCSIS 4.0 modem silicon from two major chip suppliers. It means the hardware has cleared a CableLabs interoperability milestone, which matters because cable operators and device vendors need standards-based compatibility before wider deployment. The competitive angle is simple: both MaxLinear and Broadcom now have chips that have passed the same CableLabs test. What to watch next is which DOCSIS 4.0 modem products built on these chips appear in operator qualification or commercial deployment.
