8 / 54 page  V A AGND To Internal Circuitry I/O LM98640QML-SP SNAS461D – MAY 2010 – REVISED SEPTEMBER 2015 www.ti.com 6.6 LM98640QML Electrical Characteristics (1) (2) The following specifications apply for VDD33 = 3.3V, VDD18 = 1.8V, CL = 10pF, and fINCLK = 40MHz unless otherwise specified. SUB- PARAMETER TEST CONDITIONS NOTES MIN TYP(3) MAX UNIT GROUPS CMOS DIGITAL INPUT DC SPECIFICATIONS (SCLK, SEN, SDI, CLPIN) VIH Logical “1” Input Voltage 1, 2, 3 2.0 V VIL Logical “0” Input Voltage 1, 2, 3 0.8 V CLPIN 70 100 μA Logical “1” Input Current IIH SCLK, SDI 1, 2, 3 40 300 nA VIH = VDD33 SEN 0.2 6 μA CLPIN -300 -85 nA Logical “0” Input Current IIL SCLK, SDI 1, 2, 3 -300 -50 nA VIL = VSS SEN -100 -70 μA CMOS DIGITAL OUTPUT DC SPECIFICATIONS (SDO) VOH Logical "1" Output Voltage IOUT = -0.5 mA 1, 2, 3 1.8 1.93 V VOL Logical "0" Output Voltage IOUT = 1.6 mA 1, 2, 3 0.05 0.2 V IOH Output Leakage Current VOUT = VDD 1, 2, 3 20 50 nA IOL Output Leakage Current VOUT = VSS 1, 2, 3 -50 -20 nA LVDS CLOCK RECEIVER DC SPECIFICATIONS (INCLK+ and INCLK- Pins) Differential LVDS Clock RL = 100 Ω VIHL 1, 2, 3 100 250 mV VCM (LVDS Input Common High Threshold Voltage Mode Voltage) = 1.25V Differential LVDS Clock RL = 100 Ω VILL 1, 2, 3 -250 -100 mV VCM (LVDS Input Common Low Threshold Voltage Mode Voltage) = 1.25V Diffferential LVDS Clock Input IIHL VIH = VDD33 1, 2, 3 70 100 μA Current Diffferential LVDS Clock Input IILL VIL = VSS 1, 2, 3 -49 -34 μA Current (1) The analog inputs are protected as shown below. Input voltage magnitudes beyond the supply rails will not damage the device, provided the current is limited per Note 2 under the LM98640QML Electrical Characteristics. However, input errors will be generated If the input goes above VDD33 and below VSS. (2) When the input voltage (VIN) at any pin exceeds the power supplies (VIN < VSS or VIN > VDD33), the current at that pin should be limited to 25 mA. The 50 mA maximum package input current rating limits the number of pins that can simultaneously safely exceed the power supplies with an input current of 25 mA to two. (3) Typical figures are at TA = 25°C, and represent most likely parametric norms at the time of product characterization. The typical specifications are not ensured. 8 Submit Documentation Feedback Copyright © 2010–2015, Texas Instruments Incorporated Product Folder Links: LM98640QML-SP |
