HDTV needs amplifiers, data converters, and matrix switches to handle legacy analog content.
New analog/mixed-signal chips cost less, use less power, and meet dual-supply specs while running off a single, lower-voltage supply rail.
WiMAX defines new RF-mixer requirements, but as
GSM evolves, it needs new mixer designs too.
In the U.S., new regulations that let regional Bell operating companies compete with cable to deliver video create new opportunities for ICs, enabling RF overlay on new fiber-to-the home.
HDTV on cell phones? Delivery approaches vary, and real-time live-content delivery could double the number of pico basestations—at least in Japan.
Not all drivers are consumer-related. A 22-bit ADC resolution means digital X-rays trump film. Meanwhile, per-system demand for converters in medical imaging quadruples. Chip size and power consumption must shrink accordingly.
