4-BIT SERIAL-to-PARALLEL
CONVERTER
The SY10/100E445 are integrated 4-bit serial-to-parallel
data converters. The devices are designed to operate for
NRZ data rates of up to 2.5Gb/s. The chip generates a
divide-by-4 and a divide-by-8 clock for both 4-bit conversion
and a two-chip 8-bit conversion function. The conversion
sequence was chosen to convert the first serial bit to Q
0
,
the second to Q
1
, etc.
Two selectable serial inputs provide a loopback capability
for testing purposes when the device is used in conjunction
with the E446 parallel-to-serial converter.
The start bit for conversion can be moved using the
SYNC input. A single pulse, applied asynchronously for at
least two input clock cycles, shifts the start bit for conversion
from Q
n
to Q
n-1
by one bit. For each additional shift required,
an additional pulse must be applied to the SYNC input.
Asserting the SYNC input will force the internal clock dividers
to "swallow" a clock pulse, effectively shifting a bit from the
Q
n
to the Q
n-1
output (see Timing Diagram B).
The MODE input is used to select the conversion mode
of the device. With the MODE input LOW (or open) the
device will function as a 4-bit converter. When the mode
input is driven HIGH, the data on the output will change on
every eighth clock cycle, thus allowing for an 8-bit conversion
scheme using two E445s. When cascaded in an 8-bit
conversion scheme, the devices will not operate at the
2.5Gb/s data rate of a single device. Refer to the applications
section of this data sheet for more information on cascading
the E445.
For lower data rate applications, a V
BB
reference voltage
is supplied for single-ended inputs. When operating at clock
rates above 500MHz, differential input signals are
recommended. For single-ended inputs, the V
BB
pin is tied
to the inverting differential input and bypassed via a 0.01
μ
F
capacitor. The V
BB
provides the switching reference for the
input differential amplifier. The V
BB
can also be used to AC
couple an input signal.
