MIN NOM MAX UNIT (4) TDC7201 device in combined measurement mode where START1 and START2 are connected together: (a) A common REFERENCE_START signal is applied to START1 and START2 at least 12 ns before occurrence of actual START and STOP signals in Mode 1 (and at least 2 × tCLOCK before occurrence of actual Start and Stop signals in Mode 2). (b) Start signal is connected to STOP1 (c) Stop signal is connected to STOP2 (d) Two time periods T1 (REFERENCE_START to Start) and T2 (REFERENCE_START to Stop) are measured and their difference (T2- T1) is the time between Start to Stop TIMING REQUIREMENTS: ENABLE INPUT TREN Rise time for enable signal (20% to 80%) 1 to 100 ns TFEN Fall time for enable signal (20% to 80%) 1 to 100 ns TIMING REQUIREMENTS: START1, STOP1, CLOCK, START2, STOP2 TRST, TFST Maximum rise, fall time for START, STOP signals (20% to 80%) 1 ns TRXCLK, TFXCLK Maximum rise, fall time for external CLOCK (20% to 80%) 1 ns TIMING REQUIREMENTS: TRIGG1, TRIGG2 TTRIG1START1 Time from TRIG1 to START1 5 ns TTRIG2START2 Time from TRIG2 to START2 5 ns TIMING REQUIREMENTS: Measurement Mode 1 Combined Operation(4) T1STARTSTOP_Comb_Min Minimum time between START and STOP signal combined 0.25 ns TEMPERATURE TA Ambient temperature –40 85 °C TJ Junction temperature –40 85 °C (1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application report, SPRA953. 6.4 Thermal Information THERMAL METRIC(1) TDC7201 UNIT ZAX (nFBGA) 25 PINS RθJA Junction-to-ambient thermal resistance 155.1 °C/W RθJC(top) Junction-to-case (top) thermal resistance 109.5 °C/W RθJB Junction-to-board thermal resistance 114.1 °C/W ψJT Junction-to-top characterization parameter 20.8 °C/W ψJB Junction-to-board characterization parameter 110.6 °C/W |
