¡¡¡¡The ADATE305 is a complete£¬ single-chip solution that performs the pin electronic functions of the driver£¬ the comparator£¬ and the active load £¨DCL£©£¬ per pin PMU£¬ and dc levels for ATE applications. The device also contains an HVOUT driver with a VHH buffer capable of generating up to 13.5 V. The driver features three active states£º data high mode£¬ data low mode£¬ and term mode£¬ as well as an inhibit state. The inhibit state£¬ in conjunction with the integrated dynamic clamp£¬ facilitates the implementation of a high speed active termination. The ADATE305 supports two output voltage ranges£º ?2.0 V to +6.0 V and ?1.5 V to +6.0 V by adjusting the positive and negative supply voltages. The ADATE305 can be used as either a dual single-ended drive/ receive channel or a single differential drive/receive channel. Each channel of the ADATE305 features a high speed window comparator per pin for functional testing£¬ as well as a per pin PMU with FV£¬ or FI and MV£¬ or MI functions. All necessary dc levels for DCL functions are generated by on-chip 14-bit DACs. The per pin PMU features an on-chip 16-bit DAC for high accuracy and contains integrated range resistors to minimize external component counts. The ADATE305 uses a serial bus to program all functional blocks and has an on-board temperature sensor for monitoring the device temperature.
