PDI1394P25BY Overview
Key Specifications
Package: LQFP
Key Features
- Fully supports provisions of IEEE 1394–1995 Standard for high performance serial bus and the P1394a–2000 Standard1
- While unpowered and connected to the bus, will not drive TPBIAS on a connected port, even if receiving incoming bias voltage on that port
- Fully interoperable with Firewire™ and ™ implementations of the IEEE 1394 Standard.2
- Supports extended bias-handshake time for enhanced interoperability with camcorders
- Interface to link-layer controller supports both low-cost bus-holder isolation and optional Annex J electrical isolation
- Data interface to link-layer controller through 2/4/8 parallel lines at 49.152 MHz
- Low-cost 24.576 MHz crystal provides transmit, receive data at 100/200/400 Mbps, and link-layer controller clock at 49.152 MHz
- Does not require external filter capacitors for PLL
- Interoperable with link-layer controllers using 3.3 V and 5 V supplies
- Fully compliant with Open HCI requirements
