SEMICONDUCTOR TECHNICAL DATA

The MC10E/100E446 is an integrated 4-bit parallel to serial data

converter. The device is designed to operate for NRZ data rates of up to

1.3Gb/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 parallel data into a serial stream

from bit D0 to D3. A serial input is provided to cascade two E446 devices

for 8 bit conversion applications. Note that the serial output data clocks off

of the negative input clock transition.

4-BIT PARALLEL/

SERIAL CONVERTER

• On Chip Clock ÷4 and ÷8

• 1.5 Gb/s Typical Data Rate Capability

• Differential Clock and Serial Inputs

• V

Output for Single-ended Input Applications

• Asynchronous Data Synchronization

• Mode Select to Expand to 8 Bits

• Internal 75kΩ Input Pulldown Resistors

• Extended 100E V

Range of -4.2V to -5.46V

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 E446’s. 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

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 pin is tied to the inverting differential

provides the switching reference for the input differential amplifier. The V

input and bypassed via a 0.01µF capacitor. The V

can also be used to AC couple an input signal, for more information on AC coupling refer to the interfacing section of the design

guide in the ECLinPS data book.
