VCXO And Set-Top Clock Source

The MK2771-15 is a low-cost, low-jitter, high-performance VCXO and Clock Synthesizer designed for set-top boxes. The on-chip Voltage Controlled Crystal Oscillator accepts a 0 to 3 V input voltage to cause the output Clocks to vary by 100 ppm. Using IDTs patented VCXO and Analog Phase-Locked Loop (PLL) techniques, the device uses an inexpensive 13.5 MHz pullable crystal input to produce multiple output Clocks including two selectable processor Clocks a selectable Audio Clock two Communications Clocks and three fixed Clocks All Clocks are frequency locked to the 27.00 MHz output (and to each other) with zero ppm error, so any output CAN be used as the VCXO output. Packaged in 28-pin SSOP Available in Pb-free package Ideal for systems using Oaks MPEG decoders On-chip patented VCXO with pull range of 200 ppm VCXO tuning voltage of 0 to 3 V Processor frequencies include 33.3, 40, 50, 66.6, 81, and 100 MHz Audio Clocks of 8.192 MHz, 11.2896 MHz, 12.288 MHz and 18.432 MHz Zero ppm synthesis error in all Clocks (all exactly track 27 MHz VCXO) Uses an inexpensive 13.5 MHz pullable crystal Full CMOS output swings with 25 mA output drive capability at TTL levels Advanced, low-power, sub-micron CMOS process 5 V operating voltage with 3.3 V capable I/O By Integrated Device Technology
