TSB14AA1APFB

The TSB42AA4PGER is one member of the TSB42AA4 family which is designed as the second-generation 1394 backplane physical layer device that is recommended for use in all new designs instead of the first generation TSB14C01A. This device requires an external 98.304-MHz reference oscillator input for S100 asynchronous only operation or 49.152-MHz for S50 asynchronous only operation, and is not designed to drive the backplane directly; this function must be provided externally.

Features of the TSB42AA4PGER are:(1)provides a backplane 1394 environment that supports an asynchronous transfer rate of 50 or 100 Mbits/s across 2 etches; (2)single 3.3-v supply operation with 5-v tolerance on the transceiver receive interface; (3)allows utilization of 3-state drivers as well as open-collector drivers; (4)software compatible with the TSB14CO1APM; (5)enhanced compatibility with the 1394 Cable link layer. compatible with 1394-995 and 1394a-2000 link layers; PHY/link interface is 1394a compliant?
supports provisions of IEEE 1394-995; (6)extensive testability and debug functions added. expanded register set including automatic saving of ID and priority for last node winning arbitration; (7)100 MHz or 50 MHz oscillator provides transmit, receive data, and link layer controller (LLC) clocks; (8)logic performs system initialization arbitration functions. encode and decode functions included for data-strobe bit level encoding. incoming data resynchronized to local clock.; (9)operates over the extended temperature ranges of 0 to 7 (no suffix), -40 to 85 (I suffix), and; (10)-40 to 105 (T suffix); (11)packaged in the very compact 48-pin 7 x 7 x 1 mm PFB package.

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 device 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.
