250 MHz Dual Integrated DCL with Level Setting DACs, Per Pin PMU, and Per Chip VHH ADATE305 FEATURES GENERAL DESCRIPTION Driver The ADATE305 is a complete, single-chip solution that performs 3-level driver with high-Z mode and built-in clamps the pin electronic functions of the driver, the comparator, and Precision trimmed output resistance the active load (DCL), per pin PMU, and dc levels for ATE appli- Low leakage mode (typically <10 nA) cations. The device also contains an HVOUT driver with a VHH Voltage range: up to 2.0 V to +6.0 V buffer capable of generating up to 13.5 V. 1.6 ns minimum pulse width, 2 V terminated The driver features three active states: data high mode, data low 2.1 ns minimum pulse width, 3 V terminated mode, and term mode, as well as an inhibit state. The inhibit Comparator state, in conjunction with the integrated dynamic clamp, facili- Window and differential comparator tates the implementation of a high speed active termination. 500 MHz input equivalent bandwidth The ADATE305 supports two output voltage ranges: 2.0 V Load to +6.0 V and 1.5 V to +6.0 V by adjusting the positive and 12 mA maximum current capability negative supply voltages. Per pin PMU The ADATE305 can be used as either a dual single-ended drive/ Force voltage range: up to 2.0 V to +6.0 V receive channel or a single differential drive/receive channel. 5 current ranges: 32 mA, 2 mA, 200 A, 20 A, 2 A Each channel of the ADATE305 features a high speed window Levels comparator per pin for functional testing, as well as a per pin 14-bit DAC for DCL levels PMU with FV, or FI and MV, or MI functions. All necessary dc Typically < 5 mV INL (calibrated) levels for DCL functions are generated by on-chip 14-bit DACs. 16-bit DAC for PMU levels The per pin PMU features an on-chip 16-bit DAC for high Typically < 1.5 mV INL (calibrated) linearity in FV mode accuracy and contains integrated range resistors to minimize HVOUT output buffer external component counts. 0 V to 13.5 V output range 100-lead, 14 mm 14 mm, TQFP EP package The ADATE305 uses a serial bus to program all functional blocks 900 mW per channel with no load and has an on-board temperature sensor for monitoring the device temperature.
