LVPECL requires DC biasing at the receiver; the 2.25V–3.6V supply range lets it run off a common 2.5V or 3.3V rail without an intermediate regulator.
Packaged in a 6-SMD, No Lead case measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm.
LVPECL output at 77 MHz. The differential LVPECL signal is DC-coupled and requires a 50-ohm termination to Vcc – 2V at the receiver.
Yes. The supply voltage range is 2.25V to 3.6V, so both 2.5V and 3.3V rails are within spec without an external regulator.
The DSC1122 series outputs LVPECL, while the DSC1121 series outputs LVDS. Both are MEMS-based XOs with the same package and supply range — the output type is the key selection difference.
