Component qualification in accordance with JEDEC and industry standards to ensure reliable operation over an extended temperature range. This includes, but is not limited to, Highly Accelerated Stress Test (HAST) or biased 85/85, temperature cycle, autoclave or unbiased HAST, electromigration, bond intermetallic life, and mold compound life. Such qualification testing should not be viewed as justifying use of this component beyond specified performance and environmental limits.

The TSB41BA3B-EP provides the digital and analog transceiver functions needed to implement a three-port node in a cable-based IEEE 1394 network. Each cable port incorporates two differential line transceivers. The transceivers include circuitry to monitor the line conditions as needed for determining connection status, for initialization and arbitration, and for packet reception and transmission. The TSB41BA3B-EP interfaces with a link-layer controller (LLC), such as the TSB82AA2, TSB12LV21, TSB12LV26, TSB12LV32, TSB42AA4, TSB42AB4, TSB12LV01B, or TSB12LV01C. It can also be connected via cable port to an integrated 1394 Link + PHY layer such as the TSB43AB2.
The TSB41BA3B-EP is powered by a single 3.3-V supply. The core voltage supply is supplied by an internal voltage regulator to the PLLVDD-CORE and DVDD-CORE terminals. To protect the phase-locked loop (PLL) from noise, the PLLVDD-CORE terminals must be separately decoupled from the DVDD-CORE terminals. The PLLVDD-CORE terminals are decoupled with 1-µF and smaller decoupling capacitors and the DVDD-CORE terminals are separately decoupled with 1-µF and smaller decoupling capacitors. The separation between DVDD-CORE and PLLVDD-CORE must be implemented by separate power supply rails or planes.
The TSB41BA3B-EP may be powered by dual supplies, a 3.3-V supply for I/O and a core voltage supply. The core voltage supply to the PLLVDD-CORE and DVDD-CORE terminals must meet the requirements in the recommended operating conditions section of this data sheet. The PLLVDD-CORE terminals must be separated from the DVDD-CORE terminals, the PLLVDD-CORE terminals are decoupled with 1-µF and smaller decoupling capacitors, and the DVDD-CORE terminals separately decoupled with 1-µF and smaller decoupling capacitors. The separation between DVDD-CORE and PLLVDD-CORE can be implemented by separate power supply rails, or by a single power supply rail, where the DVDD-CORE and PLLVDD-CORE are separated by a filter network to keep noise from the PLLVDD-CORE supply.
The TSB41BA3B-EP requires an external 49.152-MHz crystal to generate a reference clock. The external clock drives an internal phase-locked loop (PLL), which generates the required reference signal. This reference signal provides the clock signals that control transmission of the outbound encoded information. A 49.152-MHz clock signal is supplied by the PHY to the associated LLC for synchronization of the two devices and is used for resynchronization of the received data when operating the PHY-link interface in compliance with the IEEE 1394a-2000 standard. A 98.304-MHz clock signal is supplied by the PHY to the associated LLC for synchronization of the two devices when operating the PHY-link interface in compliance with the IEEE 1394b-2002 standard. The power down (PD) function, when enabled by asserting the PD terminal high, stops operation of the PLL.
