The DSC6003 base product number covers a family of frequencies and options; the 20 MHz variant with enable/disable function is a standard catalog item, not a special order. ## 4-VFLGA — footprint and layout note 4-VFLGA package measures 1.60 mm x 1.20 mm with a seated height of 0.89 mm — this is a true chip-scale footprint that saves board space but demands a controlled solder-paste stencil for consistent fillet formation on the four land pads.","metaTitle":"DSC6003HA1B-020.0000T MEMS XO – 20 MHz, AEC-Q100, 1.8-3.3V","metaDescription":"Microchip DSC6003HA1B-020.0000T MEMS oscillator: 20 MHz CMOS, AEC-Q100, -40°C to 125°C, 1.8-3.3V supply.
