EQRD13K2J-156.250M TR

Oscillators Overview

The EQRD13K2J-156.250M TR is a standard crystal oscillator (SPXO) from the Ecliptek EQRD13 series, operating at a nominal frequency of 156.25 MHz with LVPECL output logic. It utilizes a 7mm x 5mm 6-pad SMD package and requires a 3.3V supply voltage. The device features a frequency stability of ±50 ppm over a -40°C to +85°C temperature range, inclusive of calibration tolerance, temperature stability, supply voltage changes, load variations, first-year aging, and reflow soldering effects. Key electrical characteristics include a maximum rise/fall time of 400 ps, a duty cycle of 50% ±5%, and an RMS phase jitter of 200 fs within a 12 kHz to 20 MHz bandwidth. It supports standby control via pin configuration, drawing a maximum operating current of 50 mA and a standby current of 10 μA.

Oscillators Feature Summary

• Provides low-jitter LVPECL clock signals suitable for high-speed serial data transmission applications.

Oscillators Procurement Notes

Verify that the specific part number matches the required frequency tolerance and temperature range specifications for your application. Confirm that the LVPECL output voltage levels are compatible with the receiving circuitry's input thresholds. Ensure the PCB footprint aligns with the 7mm x 5mm 6-pad SMD package dimensions to prevent mounting issues during assembly.

Oscillators Selection Notes

Select this component when a standard SPXO with LVPECL output is required for frequencies around 156.25 MHz. Consider the ±50 ppm stability rating against system timing budgets. Evaluate the need for standby control if power management is critical. Compare phase jitter performance against other oscillators in the same package size to ensure signal integrity requirements are met for the target data rate.

Oscillators Part Context

This model belongs to the EQRD13 series of surface-mount MEMS oscillators manufactured by Ecliptek. The series offers various output logic options including LVPECL, LVDS, and CMOS across different frequency ranges.
