TAT6254C - Fiber to the Premises Optimized Solution
The FTTP network increasingly offers a variety of analog and digital video service options to the home. Meeting the RF requirements at the Optical Network Unit is increasingly challenging and cost sensitive. To help ONT designers meet these challenges, TriAccess has developed a family of RFICs that cost-effectively meet the difficult gain, noise, and distortion requirements of PON systems.
At the core of all the TriAccess products are their excellent gain and noise characteristics. Today's GPON access architectures strive to maximize the optical dynamic range and RF output power, which taken together places difficult requirements on ONT receiver gain. In addition, new multimedia distribution approaches, such as MoCa (Multimedia over Coax), require higher levels of RF output to cover an increasing number of terminal devices. The TriAccess family of devices was carefully designed to provide excellent gain, noise and distortion characteristics over the full optical input range. They provide the ONT engineer the critical tools necessary to meet tough requirements.
TriAccess RFIC typical performance, in application circuit:
- High Gain: Better than 30dB gain
- High Output: Better than 20dBmV/ch output
- Low Equivalent Input Noise: 3.5pA/rtHz
- Low Distortion: -70dBc even at high levels of optical input
- Configurable for Single 12V Supply: Eliminates need for 5V ONT supply voltage
- Separate High RF Output: Easily drives a level detector used in RF automatic gain control implementations
- Enhanced GPON Optimization: Low differential input impedance supports a wide range of triplexers and 4dB tilt is compatible with advanced RF/digital multimedia distribution
TAT7461 - Drop Amplifier
The TAT7461 is a single-ended 1 GHz RFIC drop amplifier that meets requirements of North American CATV MSOs and can be deployed both in individual homes and in multiple 75 Ohm general purpose applications. The TAT7461 provides gain and impedance consistency over temperature and production volumes. It uses active bias control to improve part-to-part consistency. It complements the company's existing TAT7460 (50-2600 MHz) single ended RFIC drop amplifier designed for combined CATV and FTTH satellite RF overlay applications in global networks.
TAT7460 - Single Ended 75 Ohm Amplifier
The new TAT7460 addresses emerging CATV, FTTH, and satellite frequency applications for home and infrastructure deployments. It is a general purpose, single-ended, 75 Ohm CATV RF amplifier designed for use up to 2600 MHz (Megahertz) bandwidth and was developed for CATV networks as well as satellite and video ONU receiver applications. The TAT7460 is fabricated using a six-inch GaAs (Gallium Arsenide) pHEMT technology to provide very low noise performance and low cost.
The TAT7460 is ideally suited for single stage, home amplifier applications as well as multi-stage 75 Ohm gain block applications. It offers excellent gain flatness and return loss, covering 50-2600 MHz, making it suitable for satellite frequency applications and emerging FTTH RF overlay networks while delivering higher sensitivity and lower power consumption (6.5V, 115mA). It was specifically designed for native 75 Ohm, high bandwidth applications.
TAT7464 - Push-Pull 75 Ohm Amplifier
The new TAT7464 is a push-pull CATV amplifier designed for higher output applications, such as switched digital video edge QAM (quadrature amplitude modulation) outputs as well as multiple dwelling unit (MDU) and other fiber-deep receiver applications. It uses the core technology of the TAT7460 to maximize output in a push-pull configuration and is a general purpose, single-ended, 75 Ohm CATV RF amplifier designed for use up to 2600 MHz (Megahertz) bandwidth. In some applications, the new TAT7464 has been able to reduce power consumption by as much as 40% to 50% when compared with other Edge QAM amplifiers.
