ADV3201: 300 MHz, 32 × 32 Buffered Analog Crosspoint Switch

ADV3200/ADV3201是32 × 32模拟交叉点开关矩阵。这两款器件具有可选择的同步端钳位输入,适于交流耦合应用和2：1 OSD 插入多路复用器。ADV3200/ADV3201在5 MHz下具有-50 dB的串扰以及-80 dB的隔离度,适合于许多高密度路由应用。60 MHz的0.1 dB平坦度带宽使ADV3200/ADV3201成为复合视频开关的理想选择。

ADV3200/ADV3201的32个独立的输出缓冲器可以被置于高阻状态,以实现并行的交叉点输出,这样,在构建更大型阵列时,关闭通道给输出总线带来的负载最小。器件具有增益为+1（ADV3200）或+2（ADV3201）的两个版本,便于在后设终端负载应用中使用。器件可采用+5 V单电源、±2.5 V双电源或±3.3 V双电源供电,所有输出启用时,待机电流仅为270 mA。通过双缓冲、串行数字控制（可提供多个器件的菊花链连接）,可以执行通道切换。

ADV3200/ADV3201采用176引脚裸露焊盘LQFP封装（24 mm × 24 mm）,工作温度范围为-40°C～+85°C。The ADV3200/ADV3201 are 32 × 32 analog crosspoint switch matrices. They feature a selectable sync-tip clamp input for ac-coupled applications and an on-screen display (OSD) insertion mux. With −48 dB of crosstalk and −80 dB isolation at 5 MHz, the ADV3200/ADV3201 are useful in many high density routing applications. The 0.1 dB flatness out to 60 MHz makes the ADV3200/ADV3201 ideal for composite video switching.

The 32 independent output buffers of the ADV3200/ADV3201 can be placed into a high impedance state for paralleling crosspoint outputs so that off-channels present minimal loading to an output bus if building a larger array. The part is available in gain of +1 (ADV3200) or +2 (ADV3201) for ease of use in back-terminated load applications. A single 5 V supply, dual ±2.5 V supplies, or dual ±3.3 V supplies (G = +2) can be used while consuming only 250 mA of idle current with all outputs enabled. The channel switching is performed via a double buffered, serial digital control, which can accommodate daisy chaining of several devices.

The ADV3200/ADV3201 are packaged in a 176-lead exposed pad LQFP (24 mm × 24 mm) and are available over the extended industrial temperature range of −40°C to +85°C.
