The Puma 5 HDK incorporates four MxL241SF MPEG tuners, which helps reduce power consumption and increases cost-efficiency. The MPEG tuner is a complete integrated RF+QAM (Quadrature Amplitude Modulation) demodulator channel, utilizing MaxLinear’s advanced CMOS (Complementary metal–oxide–semiconductor) tuner functionality with TI’s industry proven QAM demodulator, allowing manufacturers to develop a broad range of products such as cable set-top boxes, modems and video gateways.
Key features and benefits of the TNETC958 Puma 5 DOCSIS 3.0 HDK:
* The Puma 5 HDK modular and frequency agile low-power RF front end supports:
o DOCSIS3.0 modular downstream channel selection providing manufacturers with the ability to scale their downstream channel BOM (Bill of materials) investment based on the application’s requirements.
o Single MT2170 wideband tuner enabling a 96MHz capture bandwidth for the four bonded downstream channels, as well as a MT1570 DOCSIS® 3.0 PGA (programmable gain amplifier) provided by Microtune®, Inc.
o Up to four additional downstream channels via MPEG tuners that feature a 1GHz tuning range and that are software configurable for 6/8MHz channel bandwidth. This feature enables the acquisition of any video or DOCSIS channel anywhere in the spectrum without the need for re-planning the RF channel lineup.
* Multiple DOCSIS 3.0 channel bonding configuration options from four downstream and four upstream (4×4) and up to 16 downstream and four (16×4) upstream supports various tiered DOCSIS applications such as low-cost wideband data, voice services and high-end gateway products.
* Supports triple-play voice, video and data products:
o Two-line voice enabled cable modem
o Up to two battery packs for lifeline voice support
o Modular attach support for video processing platforms
* Includes home networking capabilities with modular attach support for 802.11n and MoCA1.1/2.0
* Extended memory: 1GBit DDR, 2x16MB SFLASH
* Supported by TI’s field-proven DOCSIS and voice software development kits (SDK)
