Single-Chip Video Filter/Buffers from STMicroelectronics Boost Performance, Integration, and High-Volume Availability

GENEVA, Jan. 6 /PRNewswire/ -- TSH345 and TSH346 for SD and HD applications target digital TV, Blu-ray, PVR, and set-top box applications

GENEVA, Jan. 6 /PRNewswire-FirstCall/ -- Adding cost savings and supply-chain advantages to the technical benefits of integrated video filter/buffers for consumer electronic products, the TSH345 and TSH346 introduced by STMicroelectronics (NYSE: STM), a world leader in analog ICs, are pin-compatible with existing devices and take advantage of ST's high-volume production capability.

The new ICs will be used in products such as Blu-ray players, standard DVD players, PVRs, set-top boxes and digital televisions, to drive output signals to the TV screen over 75-Ohm video connections. By integrating three complete filter/buffers into a single chip, the TSH345 or TSH346 eliminate multiple discrete components used to transmit RGB signals or component video such as Y-Pb-Pr. They will also operate without the input capacitor normally added to preserve the video synchronization signal, and require only a single 5V supply. These two features deliver further cost savings and simplify product design.

The TSH345 can drive either high-definition signals at up to 30MHz or standard-definition video in progressive or interlaced formats. A stand-by pin enables convenient power-saving operation. The TSH346 is optimized for high-definition equipment. Both types are delivered in small surface-mount packages, and can be used as direct replacements or as second source for other filter/buffer ICs. The TSH345 is a replacement for the FMS6203, FMS6418, ADA4412-3, or MAX7454. The TSH346 replaces the FMS6363, ML6426-5, ADA4417-3, THS7316, or MAX9500-9501. All units are individually tested at minimum and maximum parameters to ensure optimum performance in high-volume consumer products.

The TSH345 is available at $1.3 in quantities of 1000 units, and the TSH346 is priced at $0.8 each for 1000 units. Both devices are in full production, and samples are also available.
