Epson Crystal Application Case in Automotive Systems - Partial Application of ADAS System
As an automotive electronics engineer, are you very confused about the selection of automotive grade crystals? Do you often struggle to identify your own requirements? Unable to select suitable crystals based on project characteristics? And I'm not very clear about choosing active crystals? Or passive crystal?
Epson Crystals in Automotive System Application Case - Partial Application of ADAS System. In fact, Epson has many automotive grade crystals that meet the requirements for automotive applications. Let's take an ADAS partial case to illustrate.
The following structural diagram can refer to the crystal models recommended by Epson for different parts.
01, Main Control System
The main control system IC mainly adopts passive crystals and uses Epson FA2016AA series
FA2016AA(MHz Range Crystal Unit Ultra Miniature Size Low Profile SMD)For Automotive
02, Automotive Safety System
Main frequency 20MHz-25M, using passive crystals, using Epson FA2016AA series
03, Radar System
Main frequency 20MHz/40MHz, both active and passive
1. Passive: FA2016AA; Active: SG2016SAA
2. Epson frequency programmable crystal oscillator SG-9101CGA can be used to reduce EMC interference
