The MAX3891 serializer converts 16-bit wide, 155Mbps
parallel data to 2.5Gbps serial data in ATM and
SDH/SONET applications. The MAX3891 is ideal for inter-
facing with high-speed digital circuitry. This device
accepts single-ended LVPECL data inputs and delivers
differential LVPECL data and clock outputs. An internal
2.5Gbps serial clock, synthesized by a fully integrated
PLL that accepts multiple input reference clock rates,
retimes the output data stream. The MAX3891 operates
from a single +3.3V supply and accepts differential
LVPECL reference clock rates of 155.52MHz, 77.76MHz,
51.84MHz, or 38.88MHz. A CML loopback data output is
provided to facilitate system diagnostic testing. The
MAX3891 is available in the extended temperature range
(-40°C to +85°C) in a 64-pin TQFP exposed pad (EP)
package.
