Edge QAM / DOCSIS 3.0 Headend Amplifiers

A number of broadband services have been enabled with the effective use of high-throughput DOCSIS 3.0 systems. The rollout of the DOCSIS standard and remote PHY deployments have greatly increased service capacity, which also increases demand for higher-density small footprints, low power consumption and greater spectrum both down and upstream.

TriQuint's TriAccess™ product line includes RFIC products specifically designed to meet the stringent RF requirements of DOCSIS-based Edge QAM systems. TriAccess solutions reduce power consumption up to 50% while cutting space requirements up to 80%. The following TriQuint products provide a complete set of options for low power consumption Edge QAM operation:

  • Output stage: TAT2814A, TAT7467H, TGA2807-SM, TGA2806-SM and TAT2801
  • Driver stage: AH22 and TAT7469

Energy savings offered by these products enable closer component spacing and smaller heat-sink areas, for a smaller footprint and overall reduced thermal management needs.

See the Products and Block Diagrams tabs on this page for more information on products for Edge QAM / DOCSIS 3.0.

The TriQuint Drop Amplifier IC Advantage

TriQuint’s TriAccess amplifiers are fabricated using GaAs pHEMT technology / high Gm processes with optimized gate lengths. This technology provides excellent stability, return loss and overall performance.

TAT7427B-T1
At 18 dB, the TAT7427B-T1 provides slightly higher gain than the traditional 16 dB drop amplifier to overcome filters and other devices.

TAT7430B-T1
The TAT7430B-T1 is a 22 dB gain product that provides the gain required for output of higher port count drop amplifiers.

TAT7461
The TAT7461 provides unprecedented stability and return loss performance over temperature while meeting stringent SCTE and major MSO distortion requirements. This product also delivers excellent noise level performance.

TAT7457
TriQuint's TriAccess TAT7457 is a high-performing simplified design using an off-chip feedback resistor to enable a range of gain configuration.

Fiber to the Home (FTTH) and Fiber to the Multi-Dwelling Unit (MDU) Applications

FTTH networks increasingly offer a variety of analog and digital video service options for residential and business locations. Meeting RF requirements at the optical network unit (ONU) in a cost-sensitive marketplace is more challenging than ever. To help designers meet these challenges, TriQuint and TriAccess™ have developed a family of RFICs that cost effectively meet the difficult gain, noise and distortion requirements of passive optical network (PON) systems.

Excellent gain and noise characteristics are at the center of all TriAccess™ products from TriQuint. Today’s PON access architectures with RF overlay strive to maximize optical dynamic range and RF output power, which together place difficult requirements on optical network terminal (ONT) receiver gain. In addition, new multimedia distribution approaches such as MoCa (Multimedia over Coax Alliance) require higher levels of RF output to cover an increasing number of terminal devices. TriQuint's device family is carefully designed to provide excellent gain, noise and distortion characteristics over the full optical input range. These products provide ONT engineers the critical tools they need to meet demanding design requirements.

Features and Benefits

  • Ultra low noise
  • Flexible functionality simplifies design
  • Efficient "green" power levels
  • High gain and excellent linearity

Applications

  • FTTH optical triplexers
  • RFoG and mini-node receivers 

TAT6254C, TAT6254D
The TAT6254C and TAT6254D are ideal for use throughout the industry in GPON and other RF overlay solutions, excelling in both noise performance and dynamic range. Both devices provide a wide dynamic range using a high-performing combination of differential transimpedance amplifiers and multiple stage integration. The TAT6254C pinouts provide the flexibility to cost-optimize for a variety of applications including GPON while the TAT6254D is ideally suited for multi-stage RFoG designs.

TAT6254B
TriQuint's TriAccess TAT6254B is a breakthrough RFoG / FTTH optical receiver amplifier. The TAT6254B performs with less than half the equivalent input noise (EIN) of existing market solutions, enabling network operators to significantly extend their system link budgets or realize other economies such as a smaller bill of materials. The TAT6254B is functionally and pin-compatible with the TAT6254C, although it has significantly increased gain and lower noise for all or near-all QAM deployments.
