NBSG72A数据手册集成电路（IC）的信号开关多路复用器解码器规格书PDF

描述 Description

The NBSG72A is a high-bandwidth fully differential 2 X 2 crosspoint switch with Output Level Select (OLS) capabilities. This is a part of the GigaComm family of high performance Silicon Germanium products. The device is housed in a low profile 3 X 3 mm 16-pin QFN package.Differential inputs incorporate internal 50 Ω termination resistors and accept NECL (Negative ECL), PECL (Positive ECL), LVCMOS/LVTTL, CML, or LVDS. The OLS input is used to program the peak-to-peak output amplitude between 0 and 800 mV in five discrete steps. The SELECT inputs are single-ended and can be driven with either LVECL or LVCMOS/LVTTL input levels.

• 200 ps Typical Propagation Delay (OLS = FLOAT)
• 55/45 ps Typical Rise/Fall Times (OLS = FLOAT)
• Selectable Swing PECL Output with Operating Range: VCC = 2.375 V to 3.465 V with VEE = 0 V
• Selectable Swing NECL Output with NECL Inputs with Operating Range: VCC = 0 V with VEE = −2.375 V to −3.465 V
• Selectable Output Levels (0 mV, 200 mV, 400 mV, 600 mV or 800 mV Peak-to-Peak Output)
• 50 Ω Internal Input Termination Resistors
• Single−ended LVECL or LVCMOS/LVTTL Select Inputs (SELA, SELB)
• Failure management system to automatically re-route data

应用 Application

简介

NBSG72A属于集成电路（IC）的信号开关多路复用器解码器。由制造生产的NBSG72A信号开关，多路复用器，解码器逻辑型信号开关、多路复用器和编码器 IC 可用于对以数字格式表示数据的电信号进行路由和选择。这些器件与设计用于模拟信号的类似产品有所不同，它们保留的信息表示为两个电状态之一，而不是两个外部界限内的无穷变化量。
