Preliminary Specifications
M2004-11
Frequency Synthesizer
DESCRIPTION
The M2004-11 integrates a high performance Phase
Locked Loop (PLL) with a Voltage Controlled SAW
Oscillator (VCSO) to provide a low jitter Frequency
Translator in a 9mm x 9mm surface mount package.
The M2004-11 is pin and function compatible with
the M2004-01 and in addition includes a phase
slope limiting circuit. This provides phase build-out
protection when reselecting the input clock.
The internal high “Q” SAW filter provides low jitter
signal performance and determines the maximum
output frequency of the VCSO. A programmable
output divider can divide the VCSO frequency to
achieve an output as low as 38.88MHz.
FEATURES
Pin Compatible with the M2004-01
Build-in phase slope limiter for phase
build-out protection
The input to the Frequency Translator is provided by
selecting between one of two output reference
clocks. The output frequency is an integer multiple
of the input reference frequency.
Meets Bellcore GR-253-CORE MTIE
Output Clock Frequency up to 700MHz
Differential LVPECL Outputs
Parallel and serial control of the output and
feedback dividers is provided via the configuration
logic. An external loop filter sets the PLL bandwidth
which can be optimized to provide jitter attenuation
of the input reference clock.
Internal Low-jitter SAW-based Oscillator
Intrinsic Jitter <1ps rms (12kHz - 20MHz)
Jitter Attenuation of Input Reference Clock
Dual Input MUX
