MK2771-16 Overview
Description
The MK2771-16 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 QSOP
- RoHS 5 (green) or RoHS 6 (green and lead free) compliant package
- On-chip patented VCXO with pull range of 200 ppm
- VCXO tuning voltage of 0 to 3 V
- Processor frequencies include 16.66, 20, 25, 32, 40, and 50 MHz
- Audio clocks support 32 kHz, 44.1 kHz, 48 kHz, and 96 kHz sampling rates
- 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
