The VSC6250 is intended for use in the next generation of high-speed, high-accuracy memory testers for devices such as Direct RAMBUS DRAM, SLDRAM, DDR SDRAM, and fast SSRAM. The VSC6250 provides ultra-precise timing to allow next generation memory testers to achieve excellent overall timing accuracy. Timing delays of the VSC6250 are extremely stable with respect to temperature and voltage. Proprietary circuit design and process technology reduce pattern, data, frequency, and duty-cycle dependencies to an absolute minimum. The VSC6250 requires no external DACs, which eliminates errors due to DAC reference noise and analog crosstalk, and DAC temperature and voltage drift. The VSC6250 is available in a 128-pin PQFP, 14x20mm thermally-enhanced package. |
