DESCRIPTION

■ VBB output

TheSY10/100E111AE/LEarelowskew1-to-9differential

drivers designed for clock distribution in mind. The SY10/

100E111AE/LE'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. An enable input is

also provided such that a logic HIGH disables the device by

forcing all Q outputs LOW and all Q outputs HIGH.

The E111AE/LE is 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 tpd distributions from

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

skew device.

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.

■ Enable Input

■ Voltage and temperature compensated outputs

■ 75KΩ input pulldown resistors

■ Fully compatible with Motorola MC10/100E111

■ Available in 28-pin PLCC package

BLOCK DIAGRAM

The E111AE/LE, as with most other ECL devices, can

be operated from a positive VCC supply in PECL mode.

This allows the E111AE/LE to be used for high performance

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

take advantage of the E111AE/LE'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.

1. Parametric values specified at:

-4.2V to -5.5V.

-4.75V to -5.5V.

3 volt Power Supply Range 10/100E111LE 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. Enable is defined as the propagation delay from the 50% point of a negative transition on EN to the 50% point of a positive transition on Q (or a

negative transition on Q). Disable is defined as the propagation delay from the 50% point of a positive transition on EN to the 50% point of a

negative transition on Q (or a positive transition on Q).

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

6. The set-up time is the minimum time that EN must be asserted prior to the next transition of IN/IN to prevent an output response greater than

±75mV to that IN/IN transition (see Figure 1).

7. The hold time is the minimum time that EN must remain asserted after a negative going IN or a positive going IN to prevent an output response

greater than ±75mV to that IN/IN transition (see Figure 2).

8. The release time is the minimum time that EN must be de-asserted prior to the next IN/IN transition to ensure an output response that meets the

specified IN to Q propagation delay and output transition times (see Figure 3).

9. 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 E111AE/LE, as a differential input as low as 50mV will still produce full ECL levels at the output.

10. 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)|
