2 / 14 page ![]() DA9283.006 13 July 2006 2 (14) PIN DESCRIPTION Pin Description Symbol x-coordinate y-coordinate Crystal Oscillator Output X2 186 142 Voltage Control Input VC 372 142 Power Supply Ground VSS 543 142 Crystal/Varactor Oscillator Input X1 149 920 Output Buffer Power Down Control PD 330 920 Power Supply Voltage VDD 500 920 Buffer Output OUT 919 920 Note: Because the substrate of the die is internally connected to GND, the die has to be connected to GND or left floating. Please make sure that GND is the first pad to be bonded. Pick-and-place and all component assembly are recommended to be performed in ESD protected area. Note: Pad coordinates are measured from the left bottom corner of the chip to the center of the pads. The coordinates may vary depending on sawing width and location. However, the distances between pads are accurate. ABSOLUTE MAXIMUM RATINGS Parameter Symbol Conditions Min Max Unit Note Supply Voltage VDD - VSS -0.3 5.5 V Input Pin Voltage VSS -0.3 VDD + 0.3 V Power Dissipation (max) PMAX 100 mW Storage Temperature TST -55 150 oC ESD Rating HBM 2 kV RECOMMENDED OPERATION CONDITIONS Parameter Symbol Conditions Min Typ Max Unit Note Supply Voltage VDD For 3.3 V / 5.0 V versions For 3.3 V versions 2.5 2.5 3.3 3.3 5.3 4.0 V 1) 1, 2) Supply Current IDD VDD = 2.8 V 3.2 mA 3) Operating Temperature TOP -40 +85 oC Voltage Control Line Impedance ZVC,LINE 1 M Crystal Pulling Sensitivity S 30 ppm/pF Crystal Load Capacitance CL VC = 1.65 V 10 pF 4) Note 1: It is recommended to connect a 1 nF capacitor between the VDD and VSS pins. Note 2: For 3.3 V versions MAS9283AA-AE, MAS9283AN-AR. Note 3: Value at 15MHz. At 40MHz IDD is typically 5.8 mA. Note 4: MAS9283AG – AL has a typical crystal load capacitance of 8.5 pF when VC = 2.5 V. MAS9283AT – AX has a typical crystal load capacitance of 9 pF when VC = 2.5 V. |
