4-BIT PARALLEL-TO-SERIAL
CONVERTER
The SY10/100E446 are integrated 4-bit parallel-to-
serial data converters. These devices are designed to
operate for NRZ data rates of up to a minimum of 1.3Gb/
s. The chips generate 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 parallel data into a serial stream
from bit D
0
to D
3
. A serial input is provided to cascade
two E446 devices for 8-bit conversion applications.
The SYNC input will asynchronously reset the internal
clock circuitry. This pin allows the user to reset the internal
clock conversion unit and, thus, select the start of the
conversion process.
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 internal load clock will change
on every eighth clock cycle, thus allowing for an 8-bit
conversion scheme using two E446s. When cascaded in
an 8-bit conversion scheme, the devices will not operate
at the 1.3Gb/s data rate of a single device. Refer to the
applications section of this data sheet for more information
on cascading the E446.
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.
