LOW-POWER 3V, 2.5Gbps/2.7Gbps 1:4 DESERIALIZER WITH CLOCK RECOVERY
SUNNYVALE, CA-February 18, 2003-Maxim Integrated Products
(NASDAQ: MXIM) introduces the MAX3882 3V, 2.5Gbps/2.7Gbps 1:4 deserializer with clock and data recovery and a limiting amplifier. This deserializer is ideal for converting 2.5Gbps serial data to 4-bit-wide, 622Mbps parallel data in DWDM and SDH/SONET applications. When combined with the MAX3892 4:1 serializer with clock synthesis, the MAX3882 forms a complete two-chip 2.5Gbps/2.7Gbps transceiver solution.
Operating from a single 3.3V supply, the MAX3882 accepts serial NRZ CML data inputs as low as 10mVP-P. It also delivers 622Mbps LVDS parallel data outputs, while consuming only 610mW of power. The MAX3882 does not require an external reference clock for data acquisition. The excellent 0.65UI jitter tolerance performance provides a 0.5UI margin relative to the ITU/Bellcore SDH/SONET specification. The loopback input can be connected to an external reference clock of 155MHz/167MHz or 622MHz/667MHz, maintaining a valid clock output in the absence of input data transitions. A loss-of-lock output and vertical-threshold adjustment are also provided.
The MAX3882 is available in a 36-pin QFN (6mm x 6mm) package specified over the extended temperature range (-40°C to +85°C). Prices start at $31.63 (1000-up, FOB USA). Evaluation kits are available.
