MK2771-15 Overview
Description
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.
Key Features
- Packaged in 28 pin SSOP
- Pb-free package
- Ideal for systems using Oak’s 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
