CLOCK DRIVER (w/o ENABLE)

FEATURES

DESCRIPTION

■ 5V and 3.3V power supply options

■ 200ps part-to-part skew

The SY10/100E111A/L are low skew 1-to-9 differential

driver designed for clock distribution in mind. The SY10/

100E111A/L's function and performance are similar to the

popular SY10/100E111, with the improvement of lower

jitter and the added feature of low voltage operation. It

accepts one signal input, which can be either differential or

single-ended if the VBB output is used. The signal is fanned

out to 9 identical differential outputs.

The E111A/L are specifically designed, modeled and

produced with low skew as the key goal. Optimal design

and layout serve to minimize gate to gate skew within a

device, andempiricalmodelingisusedtodetermineprocess

control limits that ensure consistent t_pddistributions from

lot to lot. The net result is a dependable, guaranteed low

skew device.

■ 50ps output-to-output skew

■ Differential design

■ VBB output

■ Voltage and temperature compensated outputs

■ 75KΩ input pulldown resistors

■ Fully compatible with Motorola MC100LVE111

■ Available in 28-pin PLCC package

BLOCK DIAGRAM

To ensure that the tight skew specification is met it is

necessary that both sides of the differential output are

terminated into 50Ω, even if only one side is being used. In

most applications, all nine differential pairs will be used and

therefore terminated. In the case where fewer that nine

pairs are used, it is necessary to terminate at least the

output pairs on the same package side as the pair(s) being

used on that side, in order to maintain minimum skew.

Failure to do this will result in small degradations of

propagation delay (on the order of 10-20ps) of the output(s)

being used which, while not being catastrophic to most

designs, will mean a loss of skew margin.

The E111A/L, as with most other ECL devices, can be

operated from a positive VCC supply in PECL mode. This

allows the E111A/L to be used for high performance clock

distribution in +5V/+3.3V systems. Designers can take

advantage of the E111A/L's performance to distribute low

skew clocks across the backplane or the board. In a PECL

environment, series or Thevenin line terminations are

typically used as they require no additional power supplies.

For systems incorporating GTL, parallel termination offers

the lowest power by taking advantage of the 1.2V supply as

terminating voltage.

3 volt Power Supply Range 10/100E111L Series: -3.0V to -3.8V.

2. The differential propagation delay is defined as the delay from the crossing points of the differential input signals to the crossing point of the

differential output signals.

3. The single-ended propagation delay is defined as the delay from the 50% point of the input signal to the 50% point of the output signal.

4. The within-device skew is defined as the worst case difference between any two similar delay paths within a single device.

5. VPP (min) is defined as the minimum input differential voltage which will cause no increase in the propagation delay. The VPP (min) is AC limited for

the E111A/L as a differential input as low as 50mV will still produce full ECL levels at the output.

6. VCMR is defined as the range within the VIH level may vary, with the device still meeting the propagation delay specification. The VIL level must be

such that the peak-to-peak voltage is less than 1.0V and greater than or equal to VPP (min).

For PECL operation: VCMR (max) = VCC – |VCMR (max)| and

VCMR (min) = VCC – |VCMR (min)|
