High Speed Converters like ADC and DAC
Description
5G will increase the communication traffic exponentially. A 5G communication network requires high-speed
and wide-band, while keeping the noise level to a minimum. This can be achieved with a high frequency
low jitter reference clock for the communication equipment. Using the above XO, customers can input a high
frequency reference (up to 500 MHz) with extremely low phase jitter and power, from a fundamental mode
crystal to achieve excellent phase noise.
