Clock Generation Chip
The MC10/100EP139 is a low skew
÷
2/4,
÷
4/5/6 clock generation chip
designed explicitly for low skew clock generation applications. The
internal dividers are synchronous to each other, therefore, the common
output edges are all precisely aligned. The device can be driven by either
a differential or singleended ECL or, if positive power supplies are used,
LVPECL input signals. In addition, by using the V
BB
output, a sinusoidal
source can be AC coupled into the device. If a singleended input is to be
used, the V
BB
output should be connected to the CLK input and bypassed
to ground via a 0.01 F capacitor.
The common enable (EN) is synchronous so that the internal dividers
will only be enabled/disabled when the internal clock is already in the
LOW state. This avoids any chance of generating a runt clock pulse on
the internal clock when the device is enabled/disabled as can happen with
an asynchronous control. The internal enable flipflop is clocked on the
falling edge of the input clock, therefore, all associated specification
limits are referenced to the negative edge of the clock input.
Upon startup, the internal flipflops will attain a random state;
therefore, for systems which utilize multiple EP139s, the master reset
(MR) input must be asserted to ensure synchronization. For systems
which only use one EP139, the MR pin need not be exercised as the
internal divider design ensures synchronization between the
÷
2/4 and the
÷
4/5/6 outputs of a single device. All V
CC
and V
EE
pins must be
externally connected to power supply to guarantee proper operation.
The 100 Series contains temperature compensation.
