MAXIM'S MULTIRATE CDR WITH LIMITING AMPLIFIER EXCEEDS ALL SONET/SDH JITTER SPECIFICATIONS
SUNNYVALE, CA-January 24, 2003-Maxim Integrated Products
(NASDAQ: MXIM) introduces the MAX3872/MAX3874 +3.3V multirate CDR with an integrated limiting amplifier. Manufactured using Maxim's second-generation in-house SiGe process, the MAX3872/MAX3874 have a small footprint, low power consumption, and loopback capability for system diagnostic testing. These devices are ideal for SONET/SDH receivers and regenerators, add/drop multiplexers, and DWDM transmission equipment.
The MAX3872 operates at all SONET rates from 155Mbps up to 2.7Gbps, as well as Ethernet data rates at 1.25Gbps/2.5Gbps. The MAX3874 is a dual-rate CDR operating at 2.488Gbps and 2.7Gbps for SONET applications. The MAX3872/MAX3874 do not require an external-reference clock to recover the data from an input signal.
Operating from a single +3.3V supply, the MAX3872/MAX3874 feature 10mV input sensitivity and exceed ANSI, ITU, and Bellcore SONET/SDH jitter specifications. The devices generates only 2.7mUIRMS jitter and have 0.65UIP-P high-frequency jitter tolerance. The MAX3872/MAX3874 have a clock holdover capability when using a selectable-external reference clock. Other features include an adjustable-threshold range and an 800mVP-P output-voltage swing.
The MAX3872/MAX3874 are available in a 5mm x 5mm 32-pin QFN package over the extended-temperature range (-40°C to +85°C). Prices for the MAX3872 start at $39.00 and $28.00 for the MAX3874 (1000-up, FOB USA). An evaluation kit is available to speed design.
