PCM1718 is fabricated on a highly advanced 0.6µ CMOS process. PCM1718 accepts 18bit normal input data format, or 16- or 18-bit I2S data format. The digital filter performs an 8X interpolation function, as well as special functions such as soft mute and digital de-emphasis. PCM1718 is suitable for a wide variety of cost-sensitive consumer applications where good performance is required. Its low cost, small size, and single power supply make it ideal for BS tuners, keyboards, MPEG audio, PCMCIA audio cards (ZV port), MIDI applications, and set-top boxes.
