That 25 MSPS rate means it can digitize a 12.5 MHz analog input bandwidth while maintaining the full 16-bit resolution — the oversampling ratio is built into the modulator architecture, so the digital filter in the receiver handles the decimation. ## Package and rework considerations for the 16-SOIC The LVDS output pair on pins 3 and 4 (typical pinout for this family) requires 100-ohm differential trace impedance on the PCB. Keep the stub length under 12 mm from the package to the first via to avoid reflections at 25 MSPS edge rates. ## Active lifecycle and compliance documentation No official second-source or pin-compatible alternative is listed in the manufacturer's cross-reference data. If a BOM hedge is needed, the functional replacement would require a different package or pinout — a board spin is necessary.","metaTitle":"ISOSD61TR Isolated Sigma-Delta Modulator, 16-bit, 25 MSPS","metaDescription":"ISOSD61TR isolated sigma-delta modulator, 16-bit resolution, 25 MSPS sampling rate, LVDS interface, -40 to +125°C.
