Digital Controlled Crystal Oscillator (DCXO)
Overview
This IP is a tunable Digital Controlled Crystal Oscillator (DCXO). Its central frequency is 13.5 MHz. It provides a 5 bits tuning signal, DCXO_CTRL[4:0]. By setting DCXO_CTRL to different values, the output frequency can be tuned in a tunable range of +/- 100ppm. Moreover, the DCXO can work in 3 different modes by setting EI and EO to different values.
