- Low-power consumption during powerdown or microlow-power sleep mode.
- Supports extended BIAS_HANDSHAKE time for enhanced interoperability with camcorders.
- While unpowered and connected to the bus, the device will not drive TPBIAS on a connected port even if receiving incoming bias voltage on that port.
- Does not require external filter capacitors for PLL.
- Does not require a separate 5 V supply for 5 V link
controller interoperability.
- Interoperable across 1394™ cable with 1394 physical layers (PHY) using 5 V supplies.
- Interoperable with 1394 link-layer controllers using 5 V supplies.
- 1394a-2000 compliant common-mode noise filter on incoming TPBIAS.
- Powerdown features to conserve energy in battery- powered applications include:
- Device powerdown pin.
- Link interface disable using LPS.
- Inactive ports power down.
- Automatic microlow-power sleep mode during suspend.
- Interface to link-layer controller supports Annex J electrical isolation as well as bus-keeper isolation.
