MC100EP32屬于集成電路（IC）的計數(shù)器除法器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC100EP32計數(shù)器，除法器計數(shù)器和除法器 IC 是數(shù)字邏輯器件，可對輸入發(fā)生的邏輯轉(zhuǎn)換進行計數(shù)，然后使用多個并行輸出重新發(fā)送累加的計數(shù)，和/或生成單個輸出信號轉(zhuǎn)換，從而對應(yīng)用某些整數(shù)數(shù)量輸入信號轉(zhuǎn)換進行響應(yīng)。除了簡單的事件計數(shù)，它們還可用于各種頻率合成應(yīng)用。

描述 Description

The MC10/100EP32 is an integrated ÷2 divider with differential CLK inputs.

The VBB pin, an internally generated voltage supply, is available to this device only. For single-ended input conditions, the unused differential input is connected to VBB as a switching reference voltage.

VBB may also rebias AC coupled inputs. When used, decouple VBB and VCC via a 0.01μF capacitor and limit current sourcing or sinking to 0.5 mA. When not used, VBB should be left open.

The reset pin is asynchronous and is asserted on the rising edge.

Upon power-up, the internal flip-flops will attain a random state; the reset allows for the synchronization of multiple EP32’s in a system.

The 100 Series contains temperature compensation.
