The DSC6111HL3B-060.0000: Typical active current is 3 mA, and the standby (power-down) mode drops consumption to 1.5 µA, making it suitable for battery-backed or intermittently powered modules that need a wake-up clock.
Surface-mount assembly on a 2-layer board is straightforward; the small outline leaves room for decoupling capacitors near the supply pin.
