SIT1532AC-J5-DCC-32.768E Crystals, Oscillators, Resonators

1. Description

SiT1532AC-J5-DCC-32.768E is the smallest and lowest power 32 kHz in the world Oscillator optimized for mobile and other battery-powered application. SiTime's silicon MEMS technology can be realized Minimal footprint and chip-scale packaging. This The device can reduce the 32 kHz footprint by up to 85% Compared with the existing 2.0 x 1.2 mm SMD XTAL package. Unlike XTAL, SiT1532AC-J5-DCC-32.768E oscillator output is enabled

Greater component placement flexibility and eliminates External load capacitor, thus saving additional components Quantity and board space. Unlike standard oscillators, SiT1532AC-J5-DCC-32.768E has NanoDrive™ (factory programmable) The output can be reduced in voltage swing to minimize power. The 1.2V to 3.63V operating power supply voltage range makes it Ideal solution for mobile applications Low-voltage battery backup power, such as button batteries or Super ceiling.

SiTime’s MEMS oscillator consists of a MEMS resonator and Programmable analog circuit. Our MEMS resonator is Manufactured using SiTime's unique MEMS First™ process. The essential The manufacturing step is EpiSeal™, during which MEMS The resonator is annealed at temperatures exceeding 1000°C. EpiSeal produces extremely strong, clean, vacuum The chamber for encapsulating the MEMS resonator and Ensure the best performance and reliability. period EpiSeal, growing a polysilicon cover on top of the resonator Cavity, no additional cover sheet required Or other peculiar packaging. As a result, SiTime’s MEMS The resonator chip can be used like any other semiconductor dead. A unique result of SiTime's MEMS First and EpiSeal The manufacturing process is the ability to integrate SiTime’s MEMS chip is equipped with SOC, ASIC, microprocessor or The analog die in the package eliminates external timing Components and provide highly integrated, smaller, Provide customers with cheaper solutions.
