 Q : 10/11 dual modulus prescaler

Does anyone know where to get 10/11 dual modulus prescalers such as the
11C90 in Europe. (Are they even being manufactured now when even
hairdryers contain microcontrollers ? :-)

I need to build a frequency synthesizer that can be programmed in decimal,
with BCD thumbwheels. ( The 64/65 or 127/128 prescalers won't do because I
can't count past $FF on my fingers)

  Motorola has many different ones.  An MC12013 is a 10/11 ECL
prescaler good to 600 MHz (typical) toggle frequency.  They cost about
$16 (US) for small quantities with a plastic case.
