11 / 67 page TSB41BA3BEP IEEE 1394b THREEPORT CABLE TRANSCEIVER/ARBITER SGLS362—MAY 2006 11 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 Terminal Functions (Continued) TERMINAL NAME TYPE PFP NO. I/O DESCRIPTION S3 CMOS 33 I Port sleep/mode selection terminal 3. On hardware reset, this terminal when used with the other five selection pins allows the user to select the speed and mode of the ports. See Table 1. Programming is done by tying the terminals high through a 1-k Ω or smaller resistor or by tying directly to ground through a 1-k Ω or smaller resistor. A bus holder is built into this terminal. S4 CMOS 32 I Port sleep/mode selection terminal 4. On hardware reset, this terminal when used with the other five selection pins allows the user to select the speed and mode of the ports. See Table 1. Programming is done by tying the terminals high through a 1-k Ω or smaller resistor or by tying directly to ground through a 1-k Ω or smaller resistor. A bus holder is built into this terminal. S5_LKON CMOS 2 I/O Port sleep/mode selection terminal 5 and link-on output. This terminal can be connected to the link- on input terminal of the LLC through a 1-k Ω resistor if the link-on input is available on the link layer. On hardware reset, this terminal when used with the other five selection pins allows the user to se- lect the speed and mode of the ports. See Table 1. A bus holder is built into this terminal. After hardware reset, this terminal is the link-on output, which notifies the LLC or other power-up logic to power up and become active. The link-on output is a square wave signal with a period of approximately 163 ns (8 PCLK cycles) when active. The link-on output is otherwise driven low, except during hardware reset when it is high impedance. The link-on output is activated if the LLC is inactive (the LPS input inactive or the LCtrl bit cleared) and when one of the following occrurs: a) The PHY receives a link-on PHY packet addressed to this node b) The PEI (port-event interrupt) register bit is 1, or c) Any of the CTOI (configuration-time-out interrupt), CPSI (cable-power-status interrupt), or d) The PHY is power-cycled and the power class is 0 through 4 Once activated, the link-on output is active until the LLC becomes active (both the LPS input active and the LCtrl bit set). The PHY also deasserts the link-on output when a bus-reset occurs unless the link-on output is otherwise active because one of the interrupt bits is set (that is, the link-on output is active due solely to the reception of a link-on PHY packet). In the case of power-cycling the PHY, the LKON signal must stop after 167 µs if the above conditions have not been met. NOTE: If an interrupt condition exists which otherwise causes the link-on output to be activated if the LLC were inactive, then the link-on output is activated when the LLC subsequently becomes inactive. TESTM CMOS 78 I Test control input. This input is used in the manufacturing test of the TSB41BA3B-EP. For normal use, this terminal must be pulled high through a 1-k Ω resistor to VDD. TPA0− TPA0+ TPB0− TPB0+ Cable 45, 46, 41, 42 I/O Port 0 twisted-pair differential-signal terminals. Board traces from each pair of positive and negative differential signal terminals must be kept matched and as short as possible to the external load resistors and to the cable connector. Request the S800 1394b layout recommendations document from your Texas Instruments representative. TPA1− TPA1+ TPB1− TPB1+ Cable 52 53 48 49 I/O Port 1 twisted-pair differential-signal terminals. Board traces from each pair of positive and negative differential signal terminals must be kept matched and as short as possible to the external load resistors and to the cable connector. Request the S800 1394b layout recommendations document from your Texas Instruments representative. |
