Each channel features individual control and status pins which eliminates the need for external microprocessor support. The matched impedance drivers reduce power consumption and provide substantial return loss to insure superior T1/E1 pulse quality. The CS61583 provides JTAG boundary scan to enhance system testability and reliability. The CS61583 is a 5 volt device and is a hardware mode derivative of the CS61584.
