Active XO for MCU clock and UART timing
The ASV-7.3728MHZ-E-T: Frequency stability is ±100ppm, which is adequate for asynchronous serial links where the baud-rate error budget must stay below the receiver's tolerance window — typically ±2.5% for UART at the standard frame; the ASV sits comfortably inside that margin. Operating range is -20°C to 70°C, placing this in the commercial-industrial band — not qualified for under-hood or outdoor-exposed enclosures without additional thermal protection on the board.
4-SMD footprint and supply current
Supplied on Tape & Reel or Cut Tape, suitable for standard SMT assembly flows — the no-lead package requires a proper reflow profile to avoid tombstoning on fine-pitch pads, so confirm the paste and oven settings match the land pattern in the manufacturer datasheet before committing a panel.
