The LMK5C33414A is a high-performance network synchronizer and jitter cleaner designed to meet the stringent requirements of wireless communications and infrastructure applications.
The device integrates three DPLLs and three APLLs to provide hitless switching and jitter attenuation with programmable loop bandwidth (LBW) and one external loop filter capacitor, maximizing flexibility and ease of use.
APLL3 features an ultra-high performance PLL with TIs proprietary Bulk Acoustic Wave (BAW) technology. The BAW APLL can generate 491.52MHz output clocks with 40fs typical / 60fs maximum RMS jitter (12kHz to 20MHz) irrespective of the DPLL reference input frequency and jitter characteristics. APLL2 and APLL1 (conventional LC VCOs) provide options for a second or third frequency and/or synchronization domain.
Reference validation circuitry monitors the DPLL reference inputs and automatically performs a hitless switch when the inputs are detected or lost. Zero-Delay Mode (ZDM) provides control over the phase relationship between inputs and outputs.
The device is fully programmable through I2C or SPI. The integrated EEPROM can be used to customize system start-up clocks. The device also features factory default ROM profiles as fallback options.
