DESCRIPTION

The SY100S811 is a low skew 1-to-9 PECL differential driver designed for clock distribution in new, high performance PECL systems. It accepts either a PECL clock input or a TTL input by using the TTL enable pin TEN. When the TTL enable pin is HIGH, the TTL input is enabled and the PECL input is disabled. When the enable pin is set LOW, the TTL input is disabled and the PECL input is enabled.
