R2S15901SP - Digital Delay-IC

General Description

R2S15901SP is a digital audio delay chip to synchronize the TV video and audio signals.

Key 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 Recommended Operating Condition Supply Voltage Range Circuit Current Operation Temperature VDD = 2.5V (typ. ) IDD = 1.0mA (typ. ) Topr=.
