Overview
Description
The XT is a quartz-based PLL oscillator with integrated TCXO with a key focus on stability. The XT family has frequency stability as tight as ±3ppm for -40 °C to +85 °C and life stability of ±13ppm. It is ideal for enterprise-level equipment that demands low noise, stable, and accurate timing/clock sources such as transceiver modules or data centers.
Short lead time, low noise, wide frequency range, excellent ambient performance, and very little engineering effort to incorporate this into your design make the XT series an excellent choice over conventional technologies. The XT family provides extremely quick delivery for both standard and custom frequencies.

Sacrifice pin XTAL32Kp.
Dear Dialog, We would like to reduce the number of layers in our print. We are using the WLCSP34, and we are not using the XTAL32K. Is it okay to sacrifice the XTAL32Kp pin, by routing the P0_7 pin through the XTAL32Kp pin? Will it impact the total power ...
