• Supports full CAV operation at 48´ speed
• Assures stable data readout by performing frame sync signal detection, protection, and interpolation.
• Demodulates the EFM signal to produce 8-bit symbol data.
• Applies a CRC check to the subcode Q signal and then outputs that signal via parallel I/O to the system microprocessor.
• Performs unscrambling and deinterleaving operations to rearrange the demodulated EFM signal in the stipulated order.
• Detects and corrects error signals and processes flags (C1: 2 errors, C2: 4 errors)
• References the C1 flags and the C2 error check result to set the C2 flags and interpolates or mutes the signal depending on the C2 flags.
• Provides two types of muting: zero-cross muting and soft muting.
• Independent left and right channel digital attenuators (8-bit resolution) Provides two types of attenuation: direct attenuation and soft attenuation.
• Bilingual support
• Built-in digital audio interface (supports both CLV and CAV)
• Built-in digital deemphasis
• Built-in 8x oversampling digital filters
• Built-in D/A converters
