DESCRIPTION

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 V

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, and

empirical modeling is used to determine process control limits

that ensure consistent t

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.

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

operated from a positive V

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.

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.

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.

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

(min) is defined as the minimum input differential voltage which will cause no increase in the propagation delay. The V

(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.

CMR

is defined as the range within the V

level may vary, with the device still meeting the propagation delay specification. The V

level

must be such that the peak-to-peak voltage is less than 1.0V and greater than or equal to V

(min).
