PURPOSE:To absorb the clock phase difference, by providing a duplicated buffer in a time division connector and using the duplicated buffers corresponding to the systems 0 and 1. CONSTITUTION:A time division connector 51 consists of buffers 58-61, a clock selector 37, a data selector 45 and a collation device 46. A time division switch of the system 0 consists of FFs 39, 41, and a clock distributor 35 of the system 1. A time division switch 53 of the system 1 consists of FFs 40, 42 and a clock distributor 36 of the system 1. The buffers 58-61 are controlled with two clocks WCK and RCK. The RCK for the buffer 58 and the WCK for the buffer 60 are clocks of the system 0 and the RCK for the buffer 59 and the WCK for the buffer 61 are clocks of the system 1. |
