High-speed amplifier targets 200Mbit/s Internet & HomePlug equipments

ST Microelectronics introduced a new broadband signal amplifier IC, TS617 that supports higher frequencies and faster response, as well as lower noise, than amplifiers used in current equipment.

Some of the key features are:

1. The TS617 supports up to 200MHz operation, which will satisfy faster broadband services such as 24Mbit/s ADSL2+, and VDSL offering up to 100Mbit/s download and upload speeds.
2. The TS617 is also optimized for use in broadband powerline networking using standards such as HomePlug 1.0 and HomePlugAV. HomePlugAV is a standard developed by the HomePlug Powerline Alliance, which will allow home entertainment devices to share internet and TV, audio and video using AC mains wiring instead of dedicated network cables.
3. In the TS617, there are two amplifiers, which allow engineers to connect a HomePlugAV module to the power line using a single TS617.
4. The amplifiers achieve low noise to maintain signal integrity even at very high frequencies.
5. Another performance highlight is the high slew rate, enabling fast response to the rapid rise and fall times of high-speed data signals.
6. The TS617 also implements an on-chip power-control block, to meet demands for power savings in consumer and business equipment.
7. The amplifiers stabilize within only one microsecond after entering or quitting power-down. This increases power savings by allowing the device to spend longer in the low-power mode.
8. When powered-down, the TS617 prevents interference from being put back onto the data input lines. This enables other equipment connected to the network to perform optimally at high speeds.
9. By operating from either a 5V or 12V supply, the TS617 can be used in PC-powered products or equipment with an independent power supply.

Availability: The TS617 is in full production now and available for the customer
Price: $1.40 each for orders over 1000 pieces
Package: SO-14 small-outline surface-mount package
