VCXO PLUS AUDIO CLOCK FOR STB DATASHEET MK3722 The MK3722 is a low cost, low jitter, high performance VCXO and PLL clock synthesizer designed to replace expensive discrete VCXOs and multipliers. The patented on-chip Voltage Controlled Crystal Oscillator accepts a 0 to V input voltage to cause the output clocks to vary by ±115 ppm. Using IDT’s analog/digital Phase-Locked Loop PLL techniques, the device uses an inexpensive 27 MHz pullable crystal input to produce a reference output and a selectable audio clock. IDT manufactures the largest variety of VCXO based timing devices for all applications. Consult IDT to eliminate VCXOs, crystals, and oscillators from your board. The frequency of the on-chip VCXO is adjusted by an external control voltage connected to VIN. Because VIN is a high impedance input, it can be driven directly from an PWM RC integrator circuit. • Packaged in 16-pin TSSOP • Available in Pb lead free package • Replaces a VCXO and oscillator • Operating voltage of 3.3V • Provides output of 27 MHz plus audio clock • Uses an inexpensive 27 MHz pullable crystal • On-chip patented VCXO with pull range of 230 ppm minimum • VCXO tuning voltage of 0 to V • Advanced, low power, sub-micron CMOS process NOTE EOL for non-green parts to occur on 5/13/10 per PDN U-09-01 Block Diagram S2:S0 3 VIN X1 27 MHz Pullable Crystal X2 PLL/Clock Synthesis Circuitry Voltage Controlled Crystal Oscillator PDTS ACLK 27MHz IDT VCXO PLUS AUDIO CLOCK FOR STB MK3722 MK3722 VCXO PLUS AUDIO CLOCK FOR STB Pin Assignment PDTS ACLK 16 Pin 4.40mm body, 0.65mm pitch TSSOP VCXO AND SYNTHESIZER Audio Clock Select Table S2 S1 S0 000 001 010 011 100 101 110 111 ACLK MHz Pin Descriptions Pin Number Pin Name PDTS ACLK Pin Type Pin Description Output Crystal connection.

VCXO PLUS AUDIO CLOCK FOR STB

DATASHEET

MK3722

The MK3722 is a low cost, low jitter, high performance VCXO and PLL clock synthesizer designed to replace expensive discrete VCXOs and multipliers. The patented on-chip Voltage Controlled Crystal Oscillator accepts a 0 to V input voltage to cause the output clocks to vary by ±115 ppm. Using IDT’s analog/digital Phase-Locked Loop PLL techniques, the device uses an inexpensive 27 MHz pullable crystal input to produce a reference output and a selectable audio clock.

IDT manufactures the largest variety of VCXO based timing devices for all applications. Consult IDT to eliminate VCXOs, crystals, and oscillators from your board.

The frequency of the on-chip VCXO is adjusted by an external control voltage connected to VIN. Because VIN is a high impedance input, it can be driven directly from an PWM RC integrator circuit.
• Packaged in 16-pin TSSOP
• Available in Pb lead free package
• Replaces a VCXO and oscillator
• Operating voltage of 3.3V
• Provides output of 27 MHz plus audio clock
• Uses an inexpensive 27 MHz pullable crystal
• On-chip patented VCXO with pull range of 230 ppm
minimum
• VCXO tuning voltage of 0 to V
• Advanced, low power, sub-micron CMOS process
