The MAX3892 is an ideal 4-bit-wide, 622Mbps parallel data to 2.5Gbps serial data serializer for DWDM and SONET/SDH applications.
The MAX3892 serializer is designed for high‑speed DWDM, SONET/SDH, and backplane interconnects. It accepts LVDS clock and data inputs and provides CML serial outputs, with an on‑chip PLL that synthesizes a 2.5 GHz or 2.7 GHz clock from reference frequencies such as 622 MHz, 155.5 MHz, 77.8 MHz, or 38.9 MHz. The device operates from a single 3.3 V supply and is offered in 44‑pin QFN and TQFN packages rated for –40 °C to +85 °C.
Key features include a 4 × 4‑bit FIFO, selectable dual VCO for low jitter, 455 mW typical power consumption, and loop‑back outputs for system diagnostics. Detailed pin descriptions, electrical characteristics, and layout recommendations are provided to aid PCB designers.
