It accepts up to five CMOS or differential inputs and delivers ten outputs in CMOS, LVDS, or LVPECL formats, with a maximum output frequency of 750 MHz. The fully differential signal path (input and output) keeps jitter low enough for 10GbE and CPRI reference clocks. Dual supply rails — 1.8 V and 3.3 V — let it sit on a mixed-voltage board without an extra regulator. The 750 MHz maximum output frequency covers most Ethernet MAC/PHY reference clocks (125 MHz, 156.25 MHz), SONET/SDH line rates up to OC-192 (622.08 MHz), and wireless base-station local oscillators in the 491.52 MHz to 737.28 MHz range. If your design needs a 1 GHz+ clock for a 100GbE gearbox or a JESD204B converter, you'd step up to a multi-PLL part like the ZL30793LFG7, which runs to 1045 MHz and adds HCSL and HSTL output options. ## Output format flexibility saves board space CMOS, LVDS, and LVPECL on the same device means one BOM line covers the FPGA bank (LVDS), the SerDes reference (LVPECL), and the general-purpose logic fan-out (CMOS). No external level translators or redundant oscillators. The 5:10 input-to-output ratio gives plenty of fan-out for a line card without adding a separate clock buffer. ## Package and power — what the layout engineer sees Supply decoupling should cover both the 1.8 V and 3.3 V rails with 0.1 µF and 1 µF caps per pin group, as recommended in the layout guide. Surface-mount only; no through-hole option. New designs can commit to it without a near-term obsolescence concern.","metaTitle":"Microchip ZL30641LDG1S PLL Clock Generator, 750 MHz","metaDescription":"Microchip ZL30641LDG1S PLL clock generator with 750 MHz max frequency, CMOS/LVDS/LVPECL outputs.
