DS3886A
Description
The DS3886A is a higher speed, lower power, pin patible version of the DS3886.
Key Features
- The backplane bus is intended to be operated with termination resistors (selected to match the bus impedance) connected to 2.1V at both ends
- The low voltage is typically 1V
- Separate ground pins are provided for each BTL output to minimize induced ground noise during simultaneous switching
- Separate QVCC and QGND pins are provided to minimize the effects of high current switching noise
- The DS3886A supports live insertion as defined in IEEE 896.2 through the LI (Live Insertion) pin
- If this function is not supported, the LI pin must be tied to the VCC pin
- The DS3886A also provides glitch free power up/down protection during power sequencing
- The DS3886A has two types of power connections in addition to the LI pin
- They are the Logic VCC (VCC) and the Quiet VCC (QVCC)
- There are two Logic VCC pins on the DS3886A that provide the supply voltage for the logic and control circuitry
