General Description
The SY100S834/L is low skew (÷1, ÷2, ÷4) or (÷2, ÷4, ÷8)
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 devices can be driven
by either a differential or single-ended ECL or, if positive
power supplies are used, PECL input signal. 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 0.01F capacitor. The
VBB output is designed to act as the switching reference
for the input of the SY100S834/L under single-ended input
conditions. As a result, this pin can only source/sink up to
0.5mA of current.
The Function Select (FSEL) input is used to determine
what clock generation chip function is. When FSEL input is
LOW, SY100S834/L functions as a divide by 2, by 4 and
by 8 clock generation chip. However, if FSEL input is
HIGH, it functions as a divide by 1, by 2 and by 4 clock
generation chip. This latter feature will increase the clock
frequency by two folds.
or (408) 955-1690
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. An internal runt pulse could
lead to losing synchronization between the internal divider
stages. 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 start-up, the internal flip-flops will attain a random
state; the master reset (MR) input allows for the
synchronization of the internal dividers, as well as for
multiple SY100S834/Ls in a system.
