The MAX3953 is a 9.953Gbps/10.3125Gbps 1:16 dese-
rializer with clock recovery for 10Gbps Ethernet and
OC192 SONET applications. The integrated phase-
locked loop (PLL) recovers a clock from the serial data
input, and the data is then retimed and demultiplexed
into 16 parallel LVDS outputs. Using Maxim’s SiGe
bipolar process, the MAX3953 can achieve 0.75UI of
high-frequency jitter tolerance comprised of 0.50UI of
deterministic jitter and 0.25UI of random jitter.
The MAX3953 includes TTL-compatible loss-of-lock
(LOL) and sync-error (SYNC_ERR) indicators that allow
the user to verify that the part has locked on to incoming
data. In case the incoming data becomes invalid, a
clock holdover function is provided to maintain a valid
reference clock to the upstream device. For proper
operation, a reference clock of baud rate/64 or baud
rate/16 is required.
The MAX3953 operates from a single +3.3V power sup-
ply and typically dissipates 1.5W. The operating tem-
perature range is from 0°C to +85°C. The MAX3953 is
available in a 68-pin QFN package.
