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

clock conversion unit and, thus, select the start of the

conversion process.

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.
