Fresco Microchip introduced the FM5150A silicon tuner for global hybrid terrestrial and cable television. The FM5150A seamlessly interfaces to TV SoCs to optimize tuner CAN and on-board designs. Samples of the Fresco FM5150A are available now for selected customers. The chip is the latest addition to Fresco’s silicon tuner product family.
The FM5150A features Fresco’s Simply RF silicon tuner architecture. The Fresco chip eliminates the effects of digital noise from microprocessors and digital processing commonly found inside existing silicon tuner designs. The FM5150A includes fully-integrated tracking filters and LNA. External input transistors, pin diodes and baluns are not required. The Fresco FM5150A offers industry-leading noise figure, superior image rejection, and intelligent real-time optimization of noise figure and return loss in cable and terrestrial environments.
The TV industry is migrating from traditional tuner CANs using hundreds of discrete components to silicon tuner-based CANs and on-board designs in order to achieve lower costs and smaller form factors. The vast majority of new tuner designs use silicon tuners. According to industry experts, nearly 50% of TV tuners shipped in 2012 will be silicon-based and will grow to over 80% by 2015.
In the past, CAN tuners included an integrated analog demodulator, digital demodulator, SAW filters and IF amplifiers. Recently, these functions have migrated from the CAN into the most popular TV system-on-chips (SoCs). At the same time, many existing silicon tuners retained some of this functionality, adding unnecessary system cost and complexity. Fresco’s Simply RF silicon tuner architecture eliminates these expensive redundant circuits to deliver the industry’s lowest system solution cost.
