DESCRIPTION

FEATURES

■ On-chip clock ÷4 and ÷8

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 D0 to D3. 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.

■ Extended 100E VEE range of –4.2V to –5.5V

■ 1.6Gb/s typical data rate capability

■ Differential clock and serial inputs

■ VBB output for single-ended use

■ Asynchronous data synchronization

■ Mode select to expand to 8 bits

■ Internal 75KΩ input pulldown resistors

■ Fully compatible with Motorola MC10E/100E446

■ Available in 28-pin PLCC package

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 VBB 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

VBB pin is tied to the inverting differential input and

bypassed via a 0.01µF capacitor. The VBB provides the

switching reference for the input differential amplifier. The

VBB can also be used to AC couple an input signal.
