Micronas is now shipping the DRX 398yZ family of digital terrestrial demodulators targeted at the rapidly growing digital television market in China. The DRX 398yZ demodulates high-definition and standard-definition television signals according to China’s GB20600-2006 standard which is also known as DTMB (Digital Television Multimedia Broadcast). The chip is highly integrated and is optimal for applications including set-top boxes, PVRs, IDTVs, Network Interface Modules (NIMs), USB-TV sticks and PC-TV cards.
“DTMB is one of the most complex broadcast transmission standards,” says Zhenning Zhang, Marketing Manager at Micronas Shanghai. “Our experience in developing advanced demodulator systems for ATSC and DVB allowed us to develop a device that exceeds all DTMB requirements and enables robust and reliable reception performance.”
The DRX 398yZ offers a high-level of integration, allowing TV makers to reduce parts cost and simplify their designs. The device requires only a single 8 MHz SAW filter, and includes PWM RF-AGC and IF-AGC outputs. It integrates a high-speed 10-bit A/D converter, a high-quality PLL which allows the use of a simple crystal as clock reference and SDRAM for de-interleaving.
