MaxLinear (NYSE:MXL) announced that Hitron Technologies is using MaxLinear DOCSIS 3.1 chips in its CODA-45 cable modem, which received DOCSIS 3.1 certification from CableLabs earlier this week.
The CODA-45 uses MaxLinear's MxL277 Full-Spectrum Capture (FSC) digital cable front-end receiver and MxL236 upstream programmable gain amplifier, as well as Intel's Puma 7 DOCSIS 3.1 SoC. The modem is designed for up to 5 Gbps downstream over multi-carrier OFDM channels bonded with 32 single-carrier QAM channels and up to 1 Gbps upstream.
The MxL277 is designed to operate up to 1.2 GHz and to support up to two OFDM channels and up to 32 QAM channels. The chip is intended for IP data gateways, home media gateways, and hybrid or IP-based set-top boxes. The MxL277 supports remote spectrum analyzer functions and SCTE 40 test scenarios for plant loading and impairment conditions.
The MxL236 cable upstream programmable gain amplifier (PGA) is designed to support upstream frequencies up to 204 MHz with any combination of OFDM and QAM channels with a combined output power of up to 65 dBmV at the cable connector. It can report network health and performance parameters on the upstream link.
"Working with Hitron to deliver multi-gigabit data rates utilizing DOCSIS 3.1 is an exciting milestone for MaxLinear," said Will Torgerson, MaxLinear's vice president and general manager, Broadband Group. "This is a great example of the value MaxLinear's Full-Spectrum Capture receivers bring to OEMs developing next-generation cable modem and gateway products. Our product features not only represent the absolute best-in-class in power savings, performance, form factor and ease of RF use, but also offer valuable network performance enhancement diagnostics to cable MSOs. We are looking forward to supporting Hitron with our MxL277 receiver and MxL236 PGA as they expand multimedia and data bandwidth in the home."
Hitron has also used MaxLinear chips in its DOCSIS 3.0 CPE line, most notably for gigabit-capable 32-channel modems.
