If the LPS input remains low for more than 26 s (1280 SYSCLK cycles), the PHY-LLC interface is put

15、 into a low-power disabled state in which the SYSCLK output is also held inactive. The PHY-LLC interface is placed into the disabled state upon hardware reset. The LLC is considered active only if both the LPS input is active and the LCtrl register bit is set to 1, and is considered inactive if eith

16、er the LPS input is inactive or the LCtrl register bit is cleared to 0. LREQ148CMOSILLC request input. The LLC uses this input to initiate a service request to the TSB41AB1. Bus holder is built into this terminal. PC0 PC1 PC2 20 21 22 16 17 18 CMOSIPower class programming inputs. On hardware reset,

17、these inputs set the default value of the power class indicated during self-ID. Programming is done by tying these terminals high or low. Refer to Table 9 for encoding. PD1412CMOSIPower-down input. A high on this terminal turns off all internal circuitry except the cable-active monitor circuits, whi

18、ch control the CNA output (64-terminal PAP package only). Asserting the PD input high also activates an internal pulldown on the RESET terminal to force a reset of the internal control logic. (PD is provided for legacy compatibility and is not recommended for power management in place of IEEE 1394a-

TYPEI/ODESCRIPTION PLLGND57, 5841SupplyPLL circuit ground terminals. These terminals should be tied together to the low-impedance circuit board ground plane.

20、PLLVDD5640SupplyPLL circuit power terminals. A combination of high-frequency decoupling capacitors near each terminal is suggested, such as paralleled 0.1 F and 0.001 F. Lower frequency 10 F filtering capacitors are also recommended. This supply terminal is separated from DVDD and AVDD inside the de

21、vice to provide noise isolation. It should be tied at a low-impedance point on the circuit board. R0 R1 40 41 33 34 BiasCurrent setting resistor terminals. These terminals are connected through an external resistor to set the internal operating currents and cable driver output currents. A resistance

22、 of 6.34 k 1.0% is required to meet the IEEE Std 1394-1995 output voltage limits. RESET5337CMOSILogic reset input. Asserting this terminal low resets the internal logic. An internal pullup resistor to VDD is provided so only an external delay capacitor is required for proper power-up operation (see

23、power-up reset in the Application Information section). The RESET terminal also incorporates an internal pulldown which is activated when the PD input is asserted high. This input is otherwise a standard logic input, and may also be driven by an open-drain type driver. SE2823CMOSITest control input.

24、 This input is used in manufacturing test of the TSB41AB1. For normal use this terminal may be tied to GND through a 1-k pulldown resistor or it may be tied to GND directly. SM2924CMOSITest control input. This input is used in manufacturing test of the TSB41AB1. For normal use this terminal should b

28、 and as short as possible to the external load resistors and to the cable connector. TPBIAS3831CableI/OTwisted-pair bias output. This provides the 1.86 V nominal bias voltage needed for proper operation of the twisted-pair cable drivers and receivers, and for signaling to the remote nodes that there

29、 is an active cable connection. XI XO 59 60 42 43 CrystalCrystal oscillator inputs. These terminals connect to a 24.576-MHz parallel resonant fundamental mode crystal. The optimum values for the external shunt capacitors are dependent on the specifications of the crystal used (see crystal selection

30、in the Application Information section). When an external clock source is used, XI should be the input and XO should be left open, and the clock must be supplied before the device is powered on.
