Description

These Clock Generation and Support clock drivers are specifically designed for driving memory arrays requiring large fanouts while operating at high speeds.

CGS2536TV meets the rise and fall time requirements of the 90 MHz and 100 MHz PentiumTM procrssors.

The CGS2536 I/O structures are CMOS. The outputs are separated into two banks of eight. One bank consists of divide by two outputs, the other, straight-through buffers. Within each bank, half the outputs are inverting, the other half non-inverting.

The CGS2536 specification guarantees part-to-part skew variation.
