IQD tau tshaj tawm qhov lawv ntseeg hais tias yog qhov tsawg tshaj plaws ntawm 32.768kHz moos oscillator nyob rau hauv tus tsim uas tseem xa tau muaj hwj chim qis heev.
Cov cuab yeej ntsuas 1.6 x 1.2 x 0.7 hli thiab tuaj nyob hauv lub hnab ntim hermetically kaw.
Nrog tam sim no noj 30μA thiab nrog ib tug standby tam sim no ntawm 3μA, lub hwj chim moos oscillator yog siv nyob rau hauv tes tuav thiab roj teeb powered daim ntawv sau npe thiab qhov twg raug yuav tsum tau nyob rau hauv lub sij hawm tiag tiag.

Cov kev siv roj xws li roj teeb kev tswj hwm, kev sib txuas lus nruab nrab ntawm lub cev thiab cov tshuab (Bluetooth, WI-nkaus, Wireless LAN & Zigbee), LCD teeb pom kev zoo thiab ntse ntsuas (AMR).

Qhov tshiab khwv muab cov cwj pwm kub zoo dua li tus qauv 32.768kHz tuning nkhaus siv los ntawm oscillators vim yog siv cov khoom siv Cry-cut-shear feem ntau pom muaj ntau zaus oscillators. Pib lub sijhawm tsuas yog 7ms ntawm 3.3V nrog rau kev nce thiab poob lub sijhawm ntawm 200ns.

Cov CMOS raws li oscillators muaj nyob rau hauv peb qhov khoom siv hluav taws xob: 1.8V (IQXO-986), 2.5V (IQXO-985) thiab 3.3V (IQXO-984) nrog cov zaus muaj zog ntawm ± 30ppm dhau ntawm kev khiav hauj lwm kub ntawm -20 mus rau 70 degrees C lossis ± 50ppm dhau -40 txog 85 degrees C.
