SP505 - WAN Multi-Mode Serial Transceiver

General Description

to DCE connectivity.

incorporates a Sipex patented (5,306,954) charge pump allowing +5V only operation.

Key Features

  • with the SP505 include internal loopback that can be initiated in either single-ended or differential modes. While in loopback mode, driver outputs are internally connected to receiver inputs creating an internal signal path convenient for diagnostic testing. This eliminates the need for an external loopback plug. The SP505 also includes a latch enable pin with the driver and receiver address decoder. Tri-state ability for the driver and receiver outputs is controlled by supplying a 4-bit word i.
