It has VHH drive capability per chip to support flash memory testing applications and integrated 16-bit DACs with an on-chip calibration engine to provide all necessary dc levels for operation of the part. The driver features three active states: data high, data low, and terminate mode, as well as a high impedance inhibit state. The inhibit state, in conjunction with the integrated dynamic clamps, facilitates the implementation of a high speed active termination. The output voltage capability is −1.5 V to +6.5 V to accommodate a wide range of ATE and instrumentation applications. The ADATE318 can be used as a dual, single-ended drive/receive channel or as a single differential drive/receive channel. Each channel of the ADATE318 features a high speed window comparator as well as a programmable threshold differential comparator for differential ATE applications. A four quadrant PPMU is also provided per channel. All dc levels for DCL and PPMU functions are generated by 24 on-chip 16-bit DACs. To facilitate accurate levels programming, the ADATE318 contains an integrated calibration function to correct gain and offset errors for each functional block. Correction coefficients can be stored on chip, and any values written to the DACs are automatically adjusted using the appropriate correction factors. The ADATE318 uses a serial programmable interface (SPI) bus to program all functional blocks, DACs, and on-chip calibration constants. It also has an on-chip temperature sensor and over/ undervoltage fault clamps for monitoring and reporting the device temperature and any output pin or PPMU voltage faults that may occur during operation.
