Silicon Tuner
STMicroelectronics announces a single-chip silicon tuner, the STB6000, which is designed to replace complex discrete component tuners in Set-Top Boxes (STBs) used for receiving digital TV or web-based material via satellite.
The RF processing circuitry is integrated onto the chip of the single 32-lead package. Whilst the tuner is a standalone functional block, it is intended to form part of a coordinated chipset with the company's STV0299 multistandard demodulator. The input frequency range of the device is 950 to 2150 MHz; it supports symbol frequency rates from 1 to 45 Msymbols/second. The chip includes fully integrated LO and PLL, differential I/Q outputs, and a buffered XO output for clocking other devices.
