Dual-frequency MEMS XO for tight timing budgets
The DSC6023HI2A-00A7: That dual-frequency output is typical for video clocking — 74.1758 MHz maps to 59.94 Hz frame rates (NTSC) and 74.25 MHz to 60 Hz (SMPTE), so a single oscillator covers both standards without a second PLL or external mux.
Package and board-fit constraints
The 4-pin LGA lands on a single row; the centre pad is not an exposed thermal paddle, so standard reflow profiles for lead-free solder apply. Supply current max is 1.3 mA typical — negligible for battery-powered designs.
Lifecycle reality — obsolete, sourced through independent channels
Microchip lists the DSC6023HI2A-00A7 as Obsolete.
