DS21448A1 Overview
The 144-BGA package reduces the amount of space on a board.To pack telecommunications equipment, the way of Tray is used.In this case, Surface Mount is the mounting type.Telecom circuit is made up of 4 circuits.When the voltage for 3.135V~3.465V is provided, improved efficiency can be achieved.Telecom switching is possible to achieve reliable performance when the operating temperature is set at 0°C~70°C.Telecom switching configuration contains 144 terminations.It requires a supply voltage of 3.3V.PCM TRANSCEIVER is the type of IC it uses for telecom.The supply current is 320mA.
DS21448A1 Features
Available in the 144-BGA package
PCM TRANSCEIVER as telecom IC type
