MC10H640, MC100H640

68030/040 PECL to TTL

Clock Driver

Description

The MC10H/100H640 generates the necessary clocks for the

68030, 68040 and similar microprocessors. It is guaranteed to meet the

clock specifications required by the 68030 and 68040 in terms of

part−to−partskew, within−part skew and also duty cycle skew.

The user has a choice of using either TTL or PECL (ECL referenced

to +5.0 V) for the input clock. TTL clocks are typically used in present

MPU systems. However, as clock speeds increase to 50 MHz and

beyond, the inherent superiority of ECL (particularly differential

ECL) as a means of clock signal distribution becomes increasingly

evident. The H640 also uses differential PECL internally to achieve its

superior skew characteristic.

The H640 includes divide−by−two and divide−by−four stages, both

to achieve the necessary duty cycle skew and to generate MPU clocks

as required. A typical 50 MHz processor application would use an

input clock running at 100 MHz, thus obtaining output clocks at

50 MHz and 25 MHz (see Logic Diagram).

Function

Reset (R): LOW on RESET forces all Q outputs LOW and all Q

outputs HIGH.

Power−Up:The device is designed to have the POS edges of the ÷ 2

and ÷ 4 outputs synchronized at power up.

Select (SEL): LOW selects the ECL input source (DE/DE). HIGH

selects the TTL input source (DT).

*For additional marking information, refer to

Application Note AND8002/D.

The H640 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.
