TSB83AA23ZAY

The TSB83AA23ZAY from Texas Instruments is an integrated IEEE 1394b OHCI Link Layer Controller (LLC) with three S800 PHY ports. This component fully supports the provisions of IEEE Std 1394b-2002, IEEE Std 1394a-2000, and IEEE Std 1394-1995 for high-performance serial bus applications. It is interoperable with Firewire™, i.LINK™, and SB1394 implementations.

Key features include three fully backward-compatible, bilingual IEEE Std 1394b-2002 cable ports operating at up to 800 Megabits per second (Mbps). The device offers full IEEE Std 1394a-2000 support, including connection debounce, arbitration acceleration, and extended resume signaling for compatibility with legacy digital video devices. It also includes power-down features for battery-powered applications and a low-power sleep mode.

The TSB83AA23ZAY is compliant with Open Host Controller Interface (OHCI) requirements and supports 3.3-V and 5-V PCI signaling environments. It operates within a temperature range of 0°C to 70°C and requires a voltage supply of 3V to 3.6V, consuming approximately 120mA. The controller is housed in a 167-NFBGA package measuring 12mm x 12mm.

This device provides fail-safe circuitry to prevent loading of TPBIAS upon sudden power loss and includes a common-mode noise filter on the incoming bias detect circuit. It is designed for applications requiring high-speed serial bus connectivity.
