LOW-POWER, COMPACT 3.3V, 10.7Gbps LIMITING AMPLIFIER
SUNNYVALE, CA-May 28, 2002-Maxim Integrated Products introduces the MAX3971A 3.3V, 10.7Gbps limiting amplifier for use in long-reach 10Gbps optical receivers. This is an improved version of the MAX3971 10.3Gbps limiting amplifier, with reduced jitter, lower power, and better sensitivity. With the MAX3970 and MAX3910 (10Gbps TIAs), the MAX3971A forms a 2-chip solution for the fiber-optic receiver modules. Manufactured using Maxim's second-generation in-house SiGe process, the MAX3971AUGP has a small footprint, ultra-low power consumption, and excellent jitter performance.
Operating from a single +3.3V supply, the MAX3971A has an input sensitivity of 2mVP-P and input overload of 1200mVP-P while consuming only 165mW of power. The MAX3971A accepts differential CML signals and provides a differential CML output with edge speeds of 20ps. The limiting amplifier generates only 1.8ps of deterministic jitter (with 800mV input) and 0.6ps of random jitter.
The MAX3971A is available in a 4mm x 4mm 20-pin QFN package or as die in the 0°C to +85°C temperature range. Prices start at $69.90 (1000-up, FOB USA). Evaluation kits are available.
