The ASH5KW delivers a CMOS output with a ±20 ppm frequency tolerance. This series has an output enable/disable feature, with a low 0.45 µA typical disable current. ▪ Wide supply voltage range: 1.6V ~ 5.5V ▪ Miniature package: 1.6 mm x 1.0 mm x 0.6 mm ▪ Low current consumption ▪ CMOS output with Tri-state function ▪ Hermetically sealed ceramic package with metal lid ▪ Suitable for RoHS compliant reflow process Features Typical Applications ▪ Internet of Things (IoT) ▪ Computers and peripherals ▪ Portable and wearable electronics ▪ Consumer electronics ▪ Industrial control and automation ▪ Mobile communication Note 1: All measurements guaranteed at Vdd = 3.0V, +25°C unless otherwise specified. Note 2: When output is enabled, the total supply current can be calculated as: Total Supply Current = (Output load [F] x Supply Voltage [V] x 32,768 [Hz]) + Disable Current [A] Example: IDD = (15 x 10-12 [F] x 3.0 [V] x 32,768 [Hz]) + 0.65 x 10-6 [A] = 1.5 µA + 0.65 µA = 2.15 µA Electrical Specifications [Note 1]
