MAX3890ECB

The MAX3890ECB is designed as one kind of +3.3V, 2.5Gbps, SDH/SONET 16:1 serializer with clock synthesis and LVDS inputs that can be used in (1)2.5Gbps SDH/SONET transmission systems; (2)2.5Gbps ATM/SONET access nodes; (3)add/drop multiplexers; (4)digital cross-connects; (5)ATM backplanes. This device belongs to the MAX3890 family that is available in the extended temperature range (-40°C to +85°C) in a 64-pin TQFP exposedpaddle (EP) package.

Features of the MAX3890ECB are:(1)single +3.3V supply; (2)495mW power consumption; (3)exceeds ANSI, ITU, and bellcore specifications; (4)155Mbps (16-bit wide) parallel to 2.5Gbps serial conversion; (5)clock synthesis for 2.5Gbps; (6)multiple clock reference frequencies (155.52MHz, 77.76MHz, 51.84MHz, 38.88MHz); (7)LVDS parallel clock and data inputs; (8)additional high-speed output for system loopback testing.

The absolute maximum ratings of the MAX3890ECB can be summarized as:(1)terminal voltage (with respect to GND) Vcc: -0.5V to +5V;(2)terminal voltage (with respect to GND) all inputs, FIL+, FIL-: -0.5V to (Vcc+0.5V);(3)lead temperature (soldering, 10sec): +300°C;(4)storage temperature range: -60°C to +150°C;(5)operating temperature range: -40°C to +85°C;(6)continuous power dissipation (TA = +85°C) TQFP-EP (derate 44.8mW/°C above +85°C): 1 W.
