Introduction

GC8418 is a CMOS monolithic receiver and converter circuit for digital audio signals, featuring an 8-to-1 input multiplexer with support for IEC60958, S/PDIF, EIAJ CP1201, and AES3 audio interfaces. The GC8418 integrates a serial digital audio output interface, interpolation filter, multi-bit DAC, and output analog filter. An internal PLL recovers a clean clock signal from the AES3 data stream.

The GC8418 is available in an SSOP28 package and supports an operating temperature range of -40°C to +85°C.

The GC8418 is a high-performance, low-cost, single-chip stereo audio receiver and converter IC. It employs single-ended analog inputs and integrates a Δ-Σ modulator, digital filter, and output analog reconstruction filter.
