Overview

The LC89075WA is a digital audio interface receiver that demodulates signals according to the data transfer format between digital audio devices via IEC60958/61937 and JEITA CPR-1205 and supports demodulation sampling frequencies of up to 192kHz. The LC89075WA also incorporates a high performance 24-bit single-end input Delta-Sigma stereo analog to digital converter that supports sampling frequencies of up to 96kHz, and an audio selector that can support 8-channel data. The LC89075WA is a complete analog and digital front-end for use in various systems including AV receivers, digital TVs, and DVD recorders.

  • Delta-Sigma stereo ADC
  • Built-in anti-aliasing digital filter
  • Single-end input (3Vp-p)
  • Built-in digital HPF for canceling DC offset
  • Built-in PGA (-4.5dB to 6dB/1.5dB step)
  • Built-in soft mute and attenuator (0dB to -63.5dB/0.25dB step, -infini)
  • Sampling frequency: 8kHz to 96kHz
  • Master clock: 512fs, 256fs (master/slave)
  • Audio data output interface: 24-bit I2S/left justified
  • Analog audio data detection (threshold level: -30dB to -60dB/adjustable in 2dB steps)

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
