New Japan Radio releases the NJM2525,
SD/HD 4-channel video driver with ground noise isolation amplifier

New Japan Radio Co., Ltd. announces the NJM2525, SD/HD*1 4-channel video driver with ground noise isolation amplifier.

[Background of development]

Recently, the increasing of Blu-ray Disc's popularity demands the video driver for analog high definition image. In home-theater and DVD-stereo market, due to cost reduction and space-saving, S-video-terminal less equipment is on the increase. The mainstream product of analog video driver in market is 6-channel driver (3ch: for component-terminal, 2ch: for S-video-terminal*2, 1ch: for composite-terminal) now. So the designers have to use only four drivers in video driver IC.

[Features]

The NJM2525 is the analog video driver developed for closing this problem. The NJM2525 consists of isolation amplifier, input selector switch, video driver (6dB amplifier, 75-ohm driver for SD image), 3ch 75-ohm driver for HD image, Y/C Mix circuit, power-save circuit and LPF selector switch. It is suitable for home-theater and DVD-stereo, capable of making space-saving of circuit board by integrating 4-channel video amplifier and selector switch into one chip.

  1. Integrating circuits suitable for home-theater into one chip helps space-saving.
  2. Isolation amplifier reducing noise of external connection equipments for keeping high quality image.
  3. Analog high definition signal corresponding for high quality image.
Notes
*1 :SD/HD:SD: Standard Definition / HD: High Definition
*2 :S-Video-Terminal:input terminal for S-video signal transmission, separated from composite signal to brightness and color signal
