N U1 General Description Features .C..A..l These minimum skew clock drivers are designed for Clock ~ PECL-TTL version of National's CGS7482528 TTL Generation & Support (CGS) applications, particularly for clock drivers ECL to TTL clock tree distribution schemes. The '2530 and - Clock Generation & Support (CGS) devices ideal for '2531 are single supply devices with guaranteed minimum ECL and TTL clock trees with CGS 100311 output skew across the outputs of a given device. Skew parameters are also provided as a means to measure duty cycle requirements as those found in high speed clocking systems. The '2530 is a minimum skew clock driver with one input driving ten outputs and the '2531 is a selectable two input to 10 outputs, specifically designed for signal generation and clock distribution applications. - 1-to-10 or 2-to-10 low skew clock distribution - 550 ps pin-to-pin output skew - Specification for transition skew to meet duty cycle re- quirements - 28-pin PCC to minimize high speed switching noise and for low dynamic power consumption - Current sourcing 48 rn A and current sinking of 64 rn A - Low dynamic power consumption above 20 MHz - Guaranteed 4 k V ESD protection Logic Symbols '2530 '2531 e KO Connection...
