SY100EL14VZC

The VBB output in the SY100EL14V chip is designed to act as the switching reference for the input of the EL14V under single-ended input conditions. It should be connected to the CLK input and bypassed to ground via a 0.01 µF capacitor. This pin can only source/sink up to 0.5mA of current when using a single-ended input.

The internal flip flop of the SY100EL14V chip is clocked on the falling edge of the input clock.

The common enable (EN) feature in the SY100EL14V chip is designed to be synchronous, ensuring that the outputs will only be enabled or disabled when they are already in the LOW state. This design choice helps to prevent the generation of a runt clock pulse that could occur with an asynchronous control . When both differential inputs are left open, the CLK input will pull down to VEE, and the CLK input will bias around VCC/2 . Overall, the SY100EL14V chip is specifically designed for low skew clock distribution applications and can be driven by either a differential or single-ended ECL input signal. It is suitable for operation in systems with power supplies ranging from 3.3V to 5.0V . In summary, the common enable (EN) feature in the SY100EL14V chip is designed to operate synchronously to ensure proper enable/disable functionality and prevent any unwanted clock pulses during operation
