Bytes are not present in the output. In their place, one bit gaps are inserted, uniformly, in the data stream. The
Reference inputs may be either RRCI/RRFI or RXCK/RXFR. The external reference frame pulse (RRFI) may
be from one to eight clock periods in duration. RTDO is output on the Falling Edge of RTCO. The order of out-
put is MSB
ally, V1 Byte times. The V1 Byte time option is enabled when the control H4INT is set to "1". For gapping
purposes, the signal is divided into nine contiguous subframes. The start of the first subframe occurs eight bit
times before RRFI or RXFR transitions Low. Each Subframe contains 720 bit times. Normally there will be 696
data bits per subframe. In this situation the resulting 24 gaps will be performed every 30 bits, with the first gap
in the subframe occurring at the thirtieth bit time. Subframes containing Pointer Decrements will contain 704
data bits and will require 16 gaps. These will be introduced every 45 bit times with the first gap occurring at the
forty-fifth bit position. Subframes containing Pointer Increments will contain 688 data bits and will require 32
gaps. These Subframes will have the gaps occurring in pairs of 22 and 23 bit times i.e., two gaps in 45 bit
times. The first gap will occur at the twenty-second bit position.
