SG2520VHN156.2500M-ECHPZA6 is a low-voltage differential signaling (LVDS) crystal oscillator designed for high-frequency timing applications. It operates at a fixed output frequency of 156.25 MHz with a supply voltage of 2.5 V ± 5%, frequency tolerance of ±20 × 10?6, and supports an output enable (OE) function for power management. The device features a compact surface-mount package measuring 2.5 × 2.0 × 0.74 mm with a 6-pin configuration, operating reliably across a temperature range of -40°C to +85°C (or -40°C to +105°C depending on grade). Key electrical characteristics include a maximum phase jitter of 50 fs (at 391 MHz < fo = 500 MHz), differential output voltage swing of 250 mV to 450 mV, and a standby current of 30 µA maximum. This oscillator is ideal for telecommunications, networking, and data center applications requiring precise clock signals with low jitter and minimal power consumption.
