Description: SHIFT_8REG是8位的一个具有移位功能的寄存器,每一次数据打入都会从这个寄存器的最低位打入,并相应进行向左移位。
ODD_110BREG是一个3位的备份寄存器,寄存器中存放的是奇数帧的同步头,也就是110。
EVEN_9BHREG是一个8位的备份寄存器,寄存器中存放的是偶数帧的同步头,也就是10011011。这两个寄存器的初始值在系统一开始就打入。
-SHIFT_8REG is eight with a displacement of the functional Register, Each will enter the data from the register into the lowest point, and the left shift accordingly. ODD_110BREG is a three backup Register, the Register is stored in the odd frame synchronization head, is 110. EVEN_9BHREG 8 is a backup Register, which register is kept even the first frame synchronization, is 10011011. This register the two initial value of the system into a start.

Description: 设计PCM30基群帧同步电路1.输入码流DATA,速率为2.04Mb/S;每帧256bit,其中前8bit为帧同步码;偶数帧的帧同步码为10011011,奇数帧的帧同步码为110XXXXX(X为任意值)。
2.系统初始状态为失步态,失步信号FLOSS输出低电平,电路在输入码流里逐比特搜寻同步码,当搜寻到第一个偶帧同步码后,电路转为逐帧搜寻,当连续三帧均正确地搜寻到同步码后,系统状态转为同步态,失步信号输出高电平;否则电路重新进入逐比特搜寻状态。
3.系统处于同步态后,当连续四帧检出的同步码均错误,则系统转为失步态,失步电路时序说明:
