DESCRIPTION
The M2006-01 integrates a high performance Phase Locked
Loop (PLL) with a Voltage Controlled SAW Oscillator (VCSO)
to provide a low jitter Frequency Synthesizer in a 9mm x
9mm surface mount package.
The internal high “Q” SAW filter provides low jitter signal
performance and determines the output frequency of the
VCSO.
Selecting between two differential LVPECL clocks or one
single-ended LVCMOS / LVTTL clock provides the input
reference signal to the Frequency Translator. The maximum
input frequency is 700MHz.
The M2006-01 will default to a multiplying factor of 32 on
power-up. The multiplying factor can be changed by serially
programming the input and feedback dividers via the
configuration logic.
A differential LVPECL signal provides the output clock for
the device. A second differential output which can be
programmed to divide the output frequency by a factor of 4
is also available. The output frequency can be momentarily
increased or decreased to add or subtract one net output
clock cycle by asserting the ADD_CLK or DROP_CLK
inputs, respectively.
An external loop filter sets the PLL bandwidth which can be
optimized to provide jitter attenuation of the input reference
clock. A phase slope limiting feature, which reduces phase
build-out in order to meet GR-253 MTIE upon an input
transient, can be manually selected by asserting the PSL
input. The phase slope limiting feature is automatically
activated whenever a new input reference clock is selected.
The frequency agility, bandwidth control, and phase slope
limiting features make the M2006-01 ideal for use as a clock
jitter attenuator, frequency translator, and clock frequency
generator in OC-3 through OC-192 applications.
