LC78845Q
Sample Rate Converter for Digital Audio
Preliminary
Overview
The LC78845Q is a synchronous sample rate converter for
digital audio signals.
Features
• Converts data sampled at 32 or 48 kHz to 44.1-kHz
sampled data.
• Passes 44.1-kHz sampled data trough without change.
• Supports 384fs and 512fs system clock rates.
• 8× oversampling filters
• Soft muting function
• Built-in PLL circuit
