Texas Instruments Discrete Semiconductor Products - Transistors - Bipolar (BJT) - Bipolar Transistor Arrays, Pre-Biased LMK61A2-644M53SIAT

The LMK61A2-644M53SIAT is a high-performance, ultra-low jitter oscillator designed to generate reference clocks for applications such as switches, routers, and FPGA interfaces. It operates from a single 3.3 V ±5% supply and supports LVDS output format at 644.53125 MHz with a total frequency tolerance of ±50 ppm. The device is packaged in a 6-pin QFM (SIA) with dimensions of 7.0 mm × 5.0 mm and operates over an industrial temperature range of -40°C to +85°C. It features ultra-low jitter of 90 fs RMS (typical) at frequencies above 100 MHz and excellent power supply ripple rejection (PSRR) of -70 dBc.
