Quality of service is key to Gigabit Ethernet ICs
The MVTX2800 family of Gigabit Ethernet switching ICs from Zarlink Semiconductor deliver full-wire speed forwarding and leading quality of service features to metropolitan optical access equipment.
The company's innovative SNIM recently won a Science and Technology Improvement Award from the Ministry of Science and Technology in Jiangsu province.
JiangSu YinHe Electronics selected Zarlink's MT312 chip for its very convenient, highly automated, channel scan feature.
When a customer installs a new satellite receiver, the MT312 chip scans, selects, and tunes digital TV channels across the complete satellite broadcast band in about 10min - with virtually no user input.
Demodulators from other vendors can take hours to perform the same function, and require consumers to input variables such as frequency, code rate and symbol rate.
"The auto scan function on the MT312 is a compelling end-user feature that differentiates our SNIM from competing products", said Wu JieMing, General Manager, Jiangsu YinHe Electronics.
"We are selling the SNIM to digital TV STB manufacturers throughout China".
The SNIM receives satellite TV signals based on the DVB-S (digital video broadcasting - satellite) standard, processes them, and outputs high-resolution MPEG-2 data.
"Our MT312 chip has the most advanced satellite auto scan capability in the industry", said Richard Yuan, Product Manager, China office, Zarlink Semiconductor.
"We make it easy for manufacturers to offer user-friendly, convenient interfaces on their satellite receivers".
The MT312 is a single-chip, variable rate digital satellite QPSK (quaternary phase shift keying) demodulator.
The device's fast auto-scan capability is achieved, in part, by a very efficient state machine that minimises software overhead on the main system processor.
The MT312 demodulator is also easy to program, and has the lowest power dissipation in its class.
The MT312 is in full production in a small, 80-pin MQFP (metric quad flat pack).
Zarlink is currently developing a next-generation satellite demodulator and tuner.
The company also offers a range of devices for DVB-T (terrestrial) products, including the MT351 and MT352 terrestrial demodulators, and the ZL10310 and ZL10311 DVB-T SoC processors.
