The vssd and vssa1 pins are connected to each other within the UCB1100. 2. The first 64 bits of the sib frame will be ‘0’, the remaining bits in the sib frame will be Hi-Z. 3. The spkrp/spkrn, tinp/tiln and toup/toutn are differential pairs. 4. The test pin contains a internal pull down. This pin should be connected to vssd in normal mode of the UCB1100. |
