SDI Reclocking Distribution Amplifier / RDA-108N AES Digital Audio Distribution Amplifier / AES-108N RDA-108N(SDI Reclocking Distribution Amplifier) 시리얼 Reclocking 디지털 신호를 분배 증폭하는 모듈로서 270 Mb/s Serial 데이터가 수용 되며, 일반적으로 270 Mb/s에서 최고 300m Cable equalization이 가능하다. 8개 출력은 2개의 그룹으로 나뉘어 그룹별 레벨 조정이 가능하며, 출력 레벨은 600mV와 1Vp-p사이에서 조정이 가능하다. "DATA" LED는 시리얼 데이타의 입력 유무를 표시하며, 입력 레벨을 나타내는"LOW SIGNAL" LED와 수평 동기 에러를 나타내는"SYNC WARNING"LED가 있다.
