Submit an RFQ with your target quantity; we will confirm current pricing and lead time from our independent distribution channel. No stock-holding is claimed — each order is quoted to your BOM line."},{"question":"What output frequencies does the DSC2044FI2-H0004 support?","answer":"It supports four selectable output frequencies: 75 MHz, 100 MHz, 125 MHz, and 150 MHz, all via a single HCSL output."},{"question":"Does the DSC2044FI2-H0004 have an enable/disable function?","answer":"Yes, it includes an enable/disable function. When disabled, the supply current drops to 23 mA max, allowing power gating of the oscillator in sleep modes."},{"question":"Is the DSC2044FI2-H0004 a direct replacement for the SiT9121?","answer":"No direct pin-compatible replacement relationship is documented. Both are MEMS-based XOs with similar frequency ranges, but the SiT9121 uses a different package and output type.
