Replace oscillator with a crystal

Problem environment

Oscillators, resonators, and crystals can be used for accurate timing in RF applications.

Steps to reproduce

  1. Observe the schematic and bill of materials
  2. Locate TCXO (XC1) connected to XTA and XTB

Expected result

The part XC1 refers to a inexpensive yet accurate (±10 ppm) crystal.

Actual result

The part XC1 refers to a expensive and hard to manage oscillator.

Severity level

This is medium priority because assembly and cost stand to benefit considerably.

A good replacement is the Murata XRCGB32M000F1H18R0 4-pin 2mm x 1,6mm crystal.
