These frequencies match the standard video clock rates used in broadcast and professional AV equipment — 74.1758MHz for NTSC-compatible 59.94 Hz frame rates, 74.25MHz for 60 Hz progressive scan. A single device covers both rates, eliminating the need for two separate oscillators on the PCB. ## MEMS resonator, 3mA max, industrial temperature range Built on a MEMS base resonator (not quartz), the DSC61XX series draws just 3mA typ at 3.63V, making it suited for power-constrained designs such as battery-operated broadcast cameras or portable test gear.","metaTitle":"DSC6121CI2A-00AJT MEMS XO, 74.1758/74.25MHz, ±25ppm","metaDescription":"DSC6121CI2A-00AJT: Microchip MEMS XO, 74.1758MHz & 74.25MHz, CMOS, ±25ppm, -40°C~85°C, 4-VDFN.
