... TxENBL[0:3] - Transmit Enable. Input, Pins 2, 78, 52, and 28. Transmit Enable: When this pin is asserted, the input data for this port, present on the TxDATA pin, is input to the CS8904 using the transmit clock, TxCLK. When this pin is deasserted, Tx+ and Tx- output pins are idle. TxDATA[0:3] - Transmit Data. Input, Pins 1, 79, 51, and 29. ...

... Ethernet specification (ISO/IEC 8802-3:1996). The CS8904 supports parallel detection. Devices that respond to the CS8904’s attempt to Auto- Negotiate with Normal Link Pulses cause the CS8904 to respond with Normal Link Pulses and to operate as a 10BASE-T half-duplex device. CS8904 has completed ...

... Auto-Negotiation was unsuccessful and that the link is failed through the Auto-Negotiation output and the Link Status LED output. Auto- negotiation may also fail if the CS8904 is unable to exchange a Link Code Word with the remote device. When Auto-Negotiation is disabled, the CS8904 sends Normal Link Pulses to the remote Ethernet device ...

... V and the crystal oscillator has stabilized. Power-Down Reset: If the supply voltage drops below approximately 2.5 V, there is a chip-wide reset. The CS8904 remains in a reset state until the power supply returns to a level greater than approximately 2.5 V and the crystal oscillator has stabilized. ...

... COLL pin to be raised. Following that, when the CS8904 detects a transition on the TxENBL pin or the termination of the data received on the Rx+/Rx- pins, then the CS8904 will cause the COLL pin to deassert. Normally, the COLL signal is used by the controller to, among other things, initiate a jam sequence ...

... No device, then a valid link will not be established and the LINKLED will be held high. 4.3.2.4 Port Loopback The CS8904 allows each individual port to be placed in a loopback mode. Note that this feature is different from MAU loopback, which is the loopback transmission of data when operating half duplex. ...
