TSB43AB23PGE

The TSB43AB23PGE from Texas Instruments is a high-performance OHCI 1.1, 1394a link layer controller. It integrates an IEEE 1394a, 400-Mbps, 3-port PHY, making it suitable for various interface applications.

This controller is designed to be fully compliant with the 1394 Open Host Controller Interface Specification (Release 1.1) and provisions of IEEE Std 1394-1995 and IEEE Std 1394a-2000. It offers features such as connection debounce, arbitrated short reset, multispeed concatenation, arbitration acceleration, fly-by concatenation, and port disable/suspend/resume capabilities.

Key electrical characteristics include a 1.8-V core logic with universal PCI interfaces compatible with 3.3-V and 5-V PCI signaling environments. It supports physical write posting of up to three outstanding transactions and PCI burst transfers. The device operates within a temperature range of 0°C to 70°C.

The TSB43AB23PGE is housed in a 144-LQFP package measuring 20x20 mm. It supports power-down features for energy conservation in battery-powered applications, including automatic device power down during suspend and PCI power management for the link-layer. It also features an ultralow-power sleep mode.
