For a 100 MHz clock, that translates to a maximum frequency error of ±2.5 kHz — tight enough for most MCU and FPGA reference inputs that do not require a TCXO or OCXO. ## Obsolete — sourcing through independent channels No official successor order code is recorded; the part is no longer available through the factory's standard distribution pipeline. For existing BOM lines that require this exact order code, supply is available through independent surplus and broker channels.","metaTitle":"DSC6121JI2A-00AHT XO, 50/100MHz, CMOS, ±25ppm, MEMS","metaDescription":"Microchip DSC6121JI2A-00AHT XO, 50MHz & 100MHz CMOS outputs, ±25ppm, 1.71-3.63V, -40-85°C, 4-VLGA.
