General Description
The MAX9486 low-cost, high-performance clock syn-
thesizer with an 8kHz input reference clock provides six
buffered LVTTL clock outputs at 35.328MHz. The clock
synthesizer can be used to generate the clocks for T1,
E1, T3, E3, and xDSL.
The MAX9486 has two phase-lock loops (PLLs). The
first PLL uses a voltage-controlled crystal oscillator
(VCXO). The second PLL is a frequency multiplier. With
the two PLLs, the MAX9486 generates the output fre-
quency at 35.328MHz. In addition, this device gener-
ates a jitter-suppressed 8kHz output that provides a
better source for the reference clock relay.
The MAX9486 is available in a 24-pin TSSOP package
and operates over the extended operating temperature
range of -40
°
C to +85
°
C and a single +3V to +3.6V
power-supply range.
Applications
Telecom Equipment Using T1, E1, T3, E3, and
ISDN Protocols
xDSL Equipment in CO with Interface to the
Telecom Protocols
