FEATURES

DESCRIPTION

■ On-chip clock ÷4 and ÷8

The SY10/100E445 are integrated 4-bit serial-to-parallel

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 Q0,

the second to Q1, etc.

Two selectable serial inputs provide a loopback capability

for testing purposes when the device is used in conjunction

with the E446 parallel-to-serial converter.

The start bit for conversion can be moved using the

SYNC input. A single pulse, applied asynchronously for at

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

from Qn to Qn-1 by one bit. For each additional shift required,

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

Qn to the Qn-1 output (see Timing Diagram B).

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

■ 2.5Gb/s 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 pull-down resistors

■ Fully compatible with Motorola MC10E/100E445

■ Available in 28-pin PLCC package

PIN CONFIGURATION

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 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.

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.
