Communications Clock PLL
GENERAL DESCRIPTION
The MK2049-10 is designed to serve as a pin
compatible, performance-improved replacement for the
MK2049-01. For full pin compatibility when using the
19.44 MHz / 38.88 MHz output selection please refer to
the MK2049-11.
The MK2049-10 is a VCXO (Voltage Controlled Crystal
Oscillator) based clock generator that produces a pin
selectable set of common telecommunications
reference frequencies. The output clock is phase
locked to an 8kHz (frame rate) input reference clock.
Features
Pin compatible upgrade for the MK2049-01
Single 5V power supply
20 pin SOIC package
Industrial temperature range
VCXO-based clock generator
Configurable jitter attenuation characteristics,
excellent for use as a Stratum source de-jitter circuit
PIN ASSIGNMENT
