    Does any know where I can find, in small quantities
    at a reasonable price, an 11C90?

    The 11C90 and 11C91 are high-speed prescalers designed specifically for
    communication and instrumentation applications. All discussions and
    examples in this data sheet are applicable to the 11C91 as well as the

    The 11C90 will divide by 10 or 11 and the 11C91 by 5 or 6, both over a
    frequency range from DC to typically 650 MHz. The division ratio is
    controlled by the Mode Control. The divide-by-10 or -11 capability
    allows the use of pulse swallowing techniques to control high-speed
    counting modulos by lower-speed circuits. The 11C90 may be used with
    either ECL or TTL power supplies.
