VCXO And HDTV Set-Top Clock Source

The MK3771-17 is a low cost, low-jitter, high-performance VCXO and Clock Synthesizer designed for set-top boxes and HDTV receivers. The on-chip Voltage Controlled Crystal Oscillator accepts a 0 to 3.3 V input voltage to cause the output Clocks to vary by 100 ppm. Using IDT's patented VCXO and Analog/Digital Phase-Locked Loop (PLL) techniques, the device uses an inexpensive 13.5 MHz crystal input to produce multiple output Clocks including selectable BCLK, a selectable Audio Clock two Communications Clocks a 13.5 MHz Clock and three 27 MHz 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 (QSOP) HDTV frequencies of 74.25 and 74.175824 MHz On-chip patented VCXO with pull range of 200 ppm minimum VCXO tuning voltage of 0 to 3.3 V Supports Ethernet with 20 and 25 MHz Clocks Modem Clocks of 11.0592 and 24.576 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 crystal Full CMOS output swings with 12 mA output drive capability at TTL levels Advanced, low power, sub-micron CMOS process 3.3 V 5% operating supply By Integrated Device Technology
