Description

DAC39RF10은 16비트 분해능의 단일 및 이중 채널 DAC(디지털-아날로그 변환기) 제품군입니다. 이 장치는 단일 채널 또는 이중 채널 비보간 DAC로 사용할 수 있습니다. 이 장치는 직접 RF 샘플링 모드 또는 기저대역 모드에서 보간 DAC로도 사용할 수 있습니다. 최대 입력 데이터 속도는 단일 채널 모드에서 20.48GSPS, 이중 채널 모드 또는 기저대역 모드에서 10.24Gsps입니다. 이 장치는 8GHz를 초과하는 반송파 주파수에서 최대 10, 7.5 및 5GHz 신호 대역폭(8, 12 및 16비트 입력 분해능)의 신호를 생성할 수 있어 C-대역을 통해 X-대역으로 직접 샘플링할 수 있습니다.
높은 샘플링 속도, 출력 주파수 범위, 64비트 NCO 주파수 분해능 및 위상 일관성이 있는 모든 주파수 호핑 덕분에 DAC39RF10은 AWG(임의 파형 생성) 및 DDS(직접 디지털 합성)가 가능합니다.
JESD204B 및 JESD204C 호환 직렬 인터페이스에는 최대 12.8Gbps까지 가능한 16개의 수신기 쌍이 있습니다. 인터페이스는 SYSREF를 사용하여 결정적 대기 시간 및 다중 장치 동기화를 위해 JESD204B 및 JESD204C 하위 클래스 1을 준수합니다.
