[1] valid if v io and (v buf or v bat ) are present. [2] trxd lines are switched as input if trxd activity is the initiator for star transmit mode. [3] pin errn provides a serial interface for retrieving diagnostic information. [4] trxd lines switched as output if txen activity is the initiator for star transmit mode. pin bge has to be connected to pin v io in order to enable the transmitter via pin txen. if pin bge is connected to ground, it is not possible to activate the transmitter via pin txen. if pin txen is not used (no controller connected to the transceiver), it has to be connected to pin v io in order to prevent txen activity detection. in all modes pin rxd is connected to the output of the normal mode receiver and therefore represents the data on the bus lines. table 10. pin signalling in star con?guration mode trxd0 / trxd1 errn rxen rxd transmitter inh1 inh2 low high low high low high star transmit output [1] input [2] error ?ag set [3] error ?ag reset [3] bus activity bus idle bus data_0 bus data_1 enabled high high star receive output disabled [1] star idle input star locked input star standby input error ?ag set [1] [3] error ?ag reset [1] [3] wake ?ag set [1] wake ?ag reset [1] wake ?ag set [1] wake ?ag reset [1] star sleep input ?oat [1] ?oat [1]

[2] all surface mount (smd) packages are moisture sensitive. depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). for details, refer to the drypack information in the data handbook ic26; integrated circuit packages; section: packing methods . table 18. suitability of surface mount ic packages for wave and re?ow soldering methods package [1] soldering method wave re?ow [2] bga, htsson..t [3] , lbga, lfbga, sqfp, ssop..t [3] , tfbga, vfbga, xson not suitable suitable dhvqfn, hbcc, hbga, hlqfp, hso, hsop, hsqfp, hsson, htqfp, htssop, hvqfn, hvson, sms not suitable [4] suitable plcc [5] , so, soj suitable suitable lqfp, qfp, tqfp not recommended [5] [6] suitable ssop, tssop, vso, vssop not recommended [7] suitable cwqccn..l [8] , pmfp [9] , wqccn..l [8] not suitable not suitable

[4] these packages are not suitable for wave soldering. on versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. on versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. [5] if wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. the package footprint must incorporate solder thieves downstream and at the side corners. [6] wave soldering is suitable for lqfp, qfp and tqfp packages with a pitch (e) larger than 0.8 mm; it is de?nitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. [7] wave soldering is suitable for ssop, tssop, vso and vssop packages with a pitch (e) equal to or larger than 0.65 mm; it is de?nitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. [8] image sensor packages in principle should not be soldered. they are mounted in sockets or delivered pre-mounted on ?ex foil. however, the image sensor package can be mounted by the client on a ?ex foil by using a hot bar soldering process. the appropriate soldering pro?le can be provided on request.
