6.1298 MHz and 6.1679 MHz output pair
The DSC6023MI2A-00AD: The two output frequencies — 6.1298 MHz and 6.1679 MHz — are spaced about 38 kHz apart, a common pattern for providing a main clock and a slightly offset reference for PLL multiplication or spread-spectrum clocking in a USB or serial-interface controller. That tight tolerance means the oscillator does not drift enough to cause bit errors in a UART or I²C link running at standard baud rates — within tolerance or it fails.
4-VFLGA footprint and integration
Decoupling is a single 100 nF ceramic between Vdd and ground, placed within 2 mm of the supply pin. Output is CMOS, so the drive strength and rise time are compatible with standard digital input thresholds without external termination — the load capacitance is the trace plus the receiver's Cin, typically under 15 pF total.
