MaxLinear Launches MxL231 and MxL235 Programmable Gain Amplifiers for Broad Range of Next-Generation DOCSIS® 3.0 and 3.1 Gateways

September 23, 2014
  • MxL231 and MxL235 Enable Lowest Power, Size and Cost for Upstream Applications Migrating to 8-Channel DOCSIS 3.0 QAM and DOCSIS 3.1 OFDM

MaxLinear, Inc. (NYSE: MXL), a leading provider of integrated radio frequency (RF) and mixed-signal integrated circuits for broadband communications applications, today announced the MxL231 and MxL235 upstream programmable gain amplifiers (PGAs) for use in DOCSIS 3.0 and upcoming DOCSIS 3.1 gateways, respectively.

PGAs are utilized to amplify upstream communications from DOCSIS gateways back to head-end equipment.

Complementing the company’s popular Full-Spectrum Capture™ (FSC™) receivers for 16-, 24-, and 32-channel DOCSIS 3.0 gateways, the MxL231 reduces front-end power dissipation by up to 1.6W compared to existing PGA offerings. As cable operators migrate from four-channel to eight-channel QAM upstream services, reducing power dissipation in the front-end simplifies thermal design efforts and reduces heat mitigation costs.

Additionally, the MxL231 is a smaller footprint than existing PGA devices and requires fewer external components, thereby reducing the PCB area required for upstream amplification. Using only a single 3.3V supply, the MxL231 now allows manufactures to eliminate the 5V supply from their gateway design entirely, simplifying layout and reducing system cost.

Leveraging similar design architecture as the MxL231, the MxL235 is optimized to meet the higher upstream power output required in the DOCSIS 3.1 standard. The MxL235 can deliver any combination of DOCSIS 3.0 and DOCSIS 3.1 channels up to a combined output power of 69dBmV. The MxL235 will be offered as a companion to MaxLinear’s upcoming DOCSIS 3.1 FSC receivers.

“We are very excited to deliver more value to our DOCSIS customers with the introduction of the MxL231 and MxL235 upstream amplifiers,” said Brian Sprague, MaxLinear’s Vice President and General Manager for Broadband and Consumer Products. “We’ve leveraged our deep expertise in low-power design to benefit our customers with reduced front-end thermal costs as cable operators expand upstream bandwidth in DOCSIS 3.0 and 3.1.”

Technical Highlights

The MxL231 supports upstream frequencies up to 85MHz with up to eight 64-QAM upstream channels and a combined output power of up to 66dBmV. In this configuration, the device dissipates less than 1W while exceeding the adjacent channel power ratio requirements in the DOCSIS 3.0 specification. The MxL231 is compatible with all 16-, 24-, and 32-channel MaxLinear DOCSIS 3.0 Full-Spectrum Capture receivers.

The MxL235 supports upstream frequencies up to 204MHz as specified in the DOCSIS 3.1 standard. The device can deliver up to 69dBmV of combined output power across any combination of QAM or OFDM upstream channels. The MxL235 is compatible with MaxLinear’s upcoming DOCSIS 3.1 Full-Spectrum Capture receivers.

Both the MxL231 and MxL235 run from a single 3.3V supply, further adding to the cost savings by eliminating the need for a 5V supply on gateway designs.

Customer samples of the MxL231 and MxL235 are available now. Please contact MaxLinear for ordering information.
