What the 25 MSPS sampling rate means for your signal chain
The ISOSD61TR is a single-channel, 16-bit isolated sigma-delta modulator with a 25 MSPS sampling rate and an LVDS data interface. 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.
