Gain Margin Design Service

Sufficient gain margin in oscillator is the key to reliable circuit design. However, most engineers do not have the time to catch up with the ever changing requirement of crystal oscillator design. Hong Kong X’tals (HKC) offers FREE crystal matching service (limited time)

Applications that require more attention in gain margin

  • RF communication products, such as WiFi, Bluetooth, RKE, TPMS
  • Safety and live concerned products, such as Airbag, ABS
  • Hi-Rel products that target at Zero (or low) defective parts per million, such as Automotive applications
