BBD-MN3010 and MN3011- is a MN3101 clock necessary?

What about a inexpensive uP e.g. ATtiny15 (dil8) or a small PIC as a clock
source,
it can easely generate the non overlaping BBD clock and the SH clock.
In case of the ATtiny; Vcc + GND + three clock outputs thats 5 out of 8 pins
used.
Remaining pins can be used as digital or analog I/O,
there is a onboard 4 chanel 10bit DAC and one timer capable of PWM (100kHz)
for the analog I/O part.
If no analog I/O is needed a $2 ATtiny10 may do.
