÷2/4, ÷4/5/6
Clock
Generation Chip
The MC100EP139 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 single–ended ECL or, if positive power supplies
are used, LVPECL input signals. In addition, by using the VBB output,
a sinusoidal source can be AC coupled into the device. If a
single–ended input is to be used, the VBB output should be connected
to the CLK input and bypassed to ground via a 0.01µF 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
flip–flop 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 flip–flops 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 VCC and VEE pins must be
externally connected to power supply to guarantee proper operation.
