The supply voltage accepts 2.5V to 3.3V, so the same part serves 2.5V and 3.3V clock domains without a separate regulator. For a remote sensor node that sleeps most of the time, the oscillator's quiescent draw is negligible against the battery's self-discharge. Active current is 7.5 mA max at 156.25 MHz — the MEMS resonator consumes less than a quartz crystal oscillator at the same frequency, which matters when the clock tree runs from a 3.3V rail with limited headroom. ## 4-VLGA package and board-level fit Housed in a 4-VLGA package measuring 2.50 mm x 2.00 mm with a seated height of 0.89 mm, this oscillator fits tight PCB stacks in handheld or multi-layer designs.","metaTitle":"DSC1502JA3A-156M2500T MEMS XO 156.25 MHz LVCMOS - Microchip","metaDescription":"Active MEMS XO, 156.25 MHz, LVCMOS output, 2.5V-3.3V supply, -40°C to 125°C, 4-VLGA.

The primary difference is the standby function — DSC1502 includes a power-down pin, while DSC1501 does not. Confirm the enable logic on your board before substituting."},{"question":"What is the standby power-down function on DSC1502JA3A-156M2500T?","answer":"Pulling the enable pin low places the oscillator in standby, reducing supply current to 1.8 µA typical.
