An Integrated Circuit Systems Company
Preliminary Specifications
M2004-02
Frequency Synthesizer
DESCRIPTION
The M2004-02 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 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
The input to the Frequency Synthesizer is provided
by selecting between a differential input clock or a
single ended input clock.
Output Clock Frequency up to 700MHz
Internal Low-jitter SAW-based Oscillator
Intrinsic Jitter <1ps rms (12kHz - 20MHz)
The output frequency is an integer multiple of the
input reference frequency. The multiplying factor is
programmed via a 6 bit parallel address.
Differential Input Compatible with LVPECL,
LVDS, HSTL, SSTL, etc.
An external loop filter sets the PLL bandwidth which
can be optimized to provide jitter attenuation of the
input reference clock.
Dual Input MUX
Parallel Programming
Tunable Loop Filter Response
Differential LVPECL Outputs
3.3V Operation
The bandwidth control, low phase noise, and HOLD
features make the M2004-02 ideal for use as a clock
jitter attenuator, frequency translator, and clock
frequency generator in OC-3 through OC-192
applications.
