The LMK61PD0A2-SIAR is an ultra-low jitter, pin-selectable differential oscillator manufactured by Texas Instruments. It operates within a supply voltage range of 3.135V to 3.465V and supports multiple output frequencies including 62.5MHz, 100MHz, 106.5MHz, 125MHz, 156.25MHz, 212.5MHz, and 312.5MHz. The device features HCSL, LVDS, and LVPECL output types with a frequency stability of ±50 ppm. It is housed in an 8-QFM (7x5mm) surface-mount package and functions reliably across an operating temperature range of -40°C to 85°C.
Verify the specific suffix against official documentation to confirm packaging and tape/reel specifications. Ensure the selected variant matches the required output frequency and interface type. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components.
Choose this component when precise frequency stability and low phase noise are critical. The pin-selectable nature simplifies inventory management by allowing one package to support multiple system configurations. Ensure the power supply voltage aligns with the specified 3.135V to 3.465V range. Consider the thermal environment to ensure operation within the -40°C to 85°C industrial temperature limits.
This oscillator belongs to the LMK61xx family of ultra-low jitter devices from Texas Instruments. These components are designed to provide robust clock signals for high-performance analog and mixed-signal systems. The family emphasizes flexibility through pin-selectable outputs, reducing design complexity and board space requirements compared to fixed-frequency alternatives.
LMK61PD0A2-SIAT is a verified substitute with identical electrical characteristics but different packaging format.
