DescriptionThe TSB42AA4PGER is one member of the TSB42AA4 family which is designed as the high performance 1394 integrated PHY and link layer controller that is compliant with the IEEE 1394-1995 and IEEE 1394a-2000 specifications and supports asynchronous transfers. This device supports the direct print protocol (DPP) and also supports the serial bus protocol 2 (SBP-2). The user can program the number of retries and the split transaction time-out value by setting the time limit register in the CFR.
Features of the TSB42AA4PGER are:(1)IEEE 1394a-2000 Compliant;(2)Single 3.3-V Supply;(3)Internal 1.8-V Circuit to Reduce Power Consumption;(4)Integrated 400-Mbps Two-Port Physical Layer (PHY);(5)Internal Voltage Regulator;(6)Ability to Support Direct Print Protocol (DPP) Mode;(7)Auto Address Increment of Direct/Indirect Addressing on Data Transfer (Packetizer);(8)8-/16-Bit Asynchronous and Synchronous DMA I/F With Handshake and Burst Mode;(9)8-/16-Bit Data/Address Multiplex Microcontroller and 8-/16-Bit Separated Data/Address Bus;(10)GGW Commercial Dual 1394 Port Package, 176-Terminal BGA.
The absolute maximum ratings of the TSB42AA4PGER can be summarized as:(1)Supply voltage range, VDD: -0.3 V to 4 V;(2)Input voltage range, VI: -0.5 V to VDD+0.5 V;(3)Output voltage range at any output: -0.5 V to VDD+0.5 V;(4)Storage temperature range: -65°C to 150°C;(5)Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds: 260°C.
The electrical characteristics of this TSB42AA4PGER can be summarized as:(1)TPBIAS output voltage: 1.665 to 2.015 V;(2)Pullup current, XRESETP input: 90 to 20 A;(3)Input current, LPS, PD, PHYTESTM, PWRCLS [0:2]: 5 A;(4)Power status threshold, CPS input: 4.7 to 7.5 V;(5)Differential output voltage: 172 to 265 mV;(6)Off-state differential voltage: 20 mV;(7)Cable bias detect threshold, TPB cable inputs: 0.6 to 1 V;(8)Positive arbitration comparator threshold voltage: 89 to 168 mV;(9)Negative arbitration comparator threshold voltage:168 to 89 mV.
