DESCRIPTION OF OPERATION
The SA702 comprises a frequency divider
circuit implemented using a divide by 4 or 5
synchronous prescaler followed by a 5 stage
synchronous counter, see BLOCK
DIAGRAM. The normal operating mode is for
MC1 (Modulus Control) to be set high and
MC2 input to be set low in which case the
circuit comprises a divide by 64. For divide
by 65 the MC1 singal is forced low, causing
the prescaler circuit to switch into divide by 5
operation for the last cycle of the
synchronous counter. For divide by 72, MC2
is set high configuring the prescaler to divide
by 4 and the counter to divide by 18. A truth
table for the modulus values is given below:
Table 1.

For minimization of propagation delay effects,
the second divider circuit is synchronous to
the divide by 4/5 stage output.
The prescaler input is positive edge sensitive,
and the output at the final count is a falling
edge with propagation delay t
PD
relative to
the input. The rising edge of the output
occurs at the count 32 with delay t
PD
.
The MC1 and MC2 inputs are TTL
compatible threshold inputs operating at a
reduced input current. CMOS and low
voltage interface capability are allowed.
The prescaler input is differential and ECL
compatible. The output is differential ECL
compatible.
