DESCRIPTION OF FUNCTION AND OPERATION
l. Entry of serial data
It Serial data used to control the IC is input through three terminals, CK, DATA and STB.
C) During the rise of a clock pulse, data is fed to the shift register in the IC in order from
the LSB.
© Upon the reception of all data, the strobe signal (STB) is made "H".
(3 After the reception of a strobe signal (STB) of the "H" level, the data stored in the shift
register is transferred to the latch in the block selected by the group code, whereby the IC
is controlled.
It The three terminal, CK, DATA and STB, contains Schmitt trigger circuits to prevent the data
errors by noise, etc.
C) Serial data group and group code
It The IC has control divided into four groups so that they may be controlled independent of
one another. Each group is identified by a 2bit group code attached at the data end.

2. Programmable dividers (CH1, CH2)
It These programmable dividers are composed of a 5bit swallow counter (5bit programmable
divider), a 12bit programmable counter, and a two-modulars prescaler providing 64 and 66
divisions.
o The strategy of a swallow counter is used to set high reference frequency.
0 Sending certain data to the swallow counter and the programmable counter allows the
setting of any of 2048 to 262142 divisions (multiple of two).
It The programmable counter and swallow counter are set by each channel. Each channel is
specified by a group code.
