MEMS XO with LVPECL at 148.5 MHz
The DSC1122BI5-148.5000: That 148.5 MHz is the standard pixel clock for 3G-SDI video links, so this part slots directly into broadcast or machine-vision timing chains without a PLL multiplier.
Active production — no LTB urgency
Microchip lists this part as Active.
Housed in a 6-SMD no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The LVPECL output requires a 50-ohm termination to Vcc - 2 V — budget two resistors per output trace. That disable current is low enough to leave the oscillator powered during a sleep state without draining a battery-backed rail.
