055TSMC_OSC_01 is a reference frequency generator designed to form a reference signal in the frequency range from 10 to 50MHz. The block consists of an amplifier, internal load capacitances, ecl-to-cmos convertor for generating CMOS output signal.
Tunable internal load capacitances (XO_C1<3:0> and XO_C2<3:0>) allow to adjust the quartz resonator frequency without using external components.
Oscillator has two modes:
• quartz mode (XTAL);
• internal generator mode (TCXO).
20 to 50 MHz crystal oscillator
