General Description
CS4103 General Description
The National Semiconductor® Geode™ CS4103 is a three port 400 Mbit/sec IEEE 1394 Physical Layer (PHY) device. The CS4103 complies to revision 2.0 of the P1394a specification. The device is a three port implementation of a reusable cell design scalable from one to sixteen ports.
The CS4103 supports all of the P1394a enhancements including connection debounce, arbitrated reset, ack-accelerated arbitration, fly-by concatenation, multi-speed packet concatenation, PHY pinging, priority arbitration, and Suspend/ Resume operation. It also implements the standard PHY-Link interface defined in IEEE specification 1394-1995 and updated in the P1394a specification for direct connection with the Geode CS4210 IEEE 1394 Open Host Controller Interface (OHCI) device. The interface can operate in either direct or isolated mode and supports single capacitor isolation with bus hold inputs.
The CS4103 provides a complete PHY solution including all bias generation, differential line drivers and receivers, single ended comparators for speed signaling, speed signaling current sources, bias detect, and connect detect circuitry per port. It includes data and strobe encoding/ decoding functions as well as a re-time FIFO to synchronize the receive data to the local clock domain. The CS4103 can receive and respond to all the PHY packet types defined in revision 2.0 of the P1394a specification. It also supports Suspend and Resume port states and connect detect functions.
The CS4103 generates the internal clocks and the Link SCLK (System Clock) based on a 24.576 MHz external crystal or a 24.576 MHz clock input. The CS4103 operates from a single 3.3V supply and supports transfers at 98.304, 196.608, and 393.216 Mbit/sec, (usually referred to as 100, 200, and 400 Mbit/sec respectively).
