Description
Features
The MK2720 is a low cost, low jitter, high
performance VCXO and PLL clock synthesizer
designed to replace expensive 13.5, 27, or 54MHz
VCXOs. The patented on-chip Voltage
Controlled Crystal Oscillator accepts a 0 to 3V
input voltage to cause the output clocks to vary by
±100 ppm. Using our patented VCXO and analog
Phase-Locked Loop (PLL) techniques, the device
uses an inexpensive external 13.5 MHz pullable
crystal input to produce output clocks of 13.5
MHz, 27 MHz, and 54 MHz .
ICS/MicroClock manufactures the largest variety
of Set-Top Box and multimedia clock synthesizers
for all applications. If more clock outputs are
needed, see the MK277x family of parts. Consult
ICS/MicroClock to eliminate VCXOs, crystals
and oscillators from your board.
Packaged in 8 pin narrow SOIC
Output clocks of 54, 27, and 13.5MHz
Uses an inexpensive 13.500 MHz external crystal
On-chip patented VCXO with pull range
of 200ppm (minimum)
VCXO tuning voltage of 0 to 3V
25mA output drive capability at TTL levels
Advanced, low power, sub-micron CMOS process
