68030/040 PECL-TTL Clock Driver
The MC10H/100H644 generates the necessary clocks for the 68030, 68040 and similar microprocessors. The device is functionally equivalent to the H640, but with fewer outputs in a smaller outline 20-lead PLCC package. It is guaranteed to meet the clock specifications required by the 68030 and 68040 in terms of part-to-part skew, within-part skew and also duty cycle skew.

The user has a choice of using either TTL or PECL (ECL referenced to FN SUFFIX +5.0V) for the input clock. TTL clocks are typically used in present MPU PLASTIC PACKAGE systems. However, as clock speeds increase to 50MHz and beyond, the CASE 775-02 inherent superiority of ECL (particularly differential ECL) as a means of clock signal distribution becomes increasingly evident. The H644 also uses differential ECL internally to achieve its superior skew characteristic. The H644 includes divide-by-two and divide-by-four stages, both to achieve the necessary duty cycle and skew to generate MPU clocks as required. A typical 50MHz processor application would use an input clock running at 100MHz, thus obtaining output clocks at 50MHz and 25MHz (see Logic Symbol). The 10H version is compatible with MECL 10HTM ECL logic levels, while the 100H version is compatible with 100K levels (referenced to +5.0V). Function
Reset (R): LOW on RESET forces all Q outputs LOW and all Q outputs HIGH. Synchronized Outputs: The device is designed to have the POS edges of the /2 and /4 outputs synchronized. Select (SEL): LOW selects the ECL input source (DE/DE). HIGH selects the TTL input source (DT). The H644 also contains circuitry to force a stable state of the ECL input differential pair, should both sides be left open. In this case, the DE side of the input is pulled LOW, and DE goes HIGH.
