CONVERTER

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

the second to Q

for testing purposes when the device is used in conjunction

with the E446 parallel-to-serial converter.

SYNC input. A single pulse, applied asynchronously for at

least two input clock cycles, shifts the start bit for conversion

from Q

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

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.
