R2S15901SP
Digital Delay IC for “Lip Sync”
Description
R2S15901SP is a digital audio delay chip to synchronize the TV video and audio signals.
Features
• CMOS Technology
• 2-Channel 24-bit Audio signals delay
• Delay time is controlled by DC voltage (9steps: 1, 7/8, 3/4, 5/8, 1/2, 3/8, 1/4, 1/8 times)
• 43K bytes RAM up to delay 224ms(@fs = 32kHz)
When fs = 48kHz, maximum delay is 149ms.
• 2 3-state pins for 9-step configuration
• 3.3V signal input available
