PDI1394P21 is a 3-port physical layer interface device released by Philips Semiconductors, which supports the IEEE 1394 standard and has a transmission speed of 100/200/400Mbps.
The Philips PDI1394P21 is an integrated circuit designed to provide digital and analog transceiver functions for implementing a three-port node in a cable-based IEEE 1394-1995 and/or 1394a network. It fully supports provisions of the IEEE 1394-1995 Standard and the P1394a supplement, including features like connection debounce, arbitrated short reset, multispeed concatenation, and arbitration acceleration.
The device operates with a single 3.3 volt supply and includes power down features to conserve energy in battery-powered applications. It interfaces with a Link Layer Controller (LLC) through parallel data lines at 49.152 MHz and utilizes a low-cost 24.576 MHz crystal for clock generation. The chip is functionally compatible with the Texas Instruments TSB41LV03.
