Frequently Asked Questions
What maximum output clock frequency does the PLL1700EG4 support, and why is that value significant for audio applications?
The PLL1700EG4 generates output clocks up to 33.8688 MHz, which is exactly 256 times the 132.3 kHz double-rate audio frequency and a standard master clock for CD-quality digital audio systems. This precise frequency enables bit-perfect sample-rate clocking for DACs operating at 44.1 kHz and its multiples, minimizing jitter-induced distortion in audio reproduction chains.
What supply voltage does the PLL1700EG4 require, and does it need any additional rails?
The PLL1700EG4 requires a 3.3 V supply for its core PLL and digital logic, and the datasheet notes an additional 3.3 V supply connection for some circuit sections. Decoupling capacitors of 100 nF placed close to each supply pin are recommended to minimize supply noise that could degrade phase noise performance of the synthesized 33.8688 MHz output clock.
How does the SSOP-20 package of the PLL1700EG4 compare to a standard SOIC-20 in terms of PCB space savings?
The SSOP-20 package uses a 0.635 mm lead pitch versus the 1.27 mm pitch of a standard SOIC-20, roughly halving the package footprint. This allows designers to place the PLL1700EG4 closer to the audio DAC or DSP it clocks, reducing clock line stub length and parasitic capacitance that could degrade signal integrity at 33 MHz frequencies.
In which audio equipment categories is the PLL1700EG4 most commonly designed in, and what alternatives exist for higher-frequency requirements?
The PLL1700EG4 is a natural fit for CD players, DVD audio decks, and standalone DAC boards where 33.8688 MHz or 22.5792 MHz master clocks are standard. For systems requiring higher audio clocks such as 49.152 MHz for 192 kHz sampling, designers typically migrate to multi-output clock synthesizers like the TI CDCE906 or similar PLLs with broader output frequency ranges and 3.3 V or 1.8 V supply options.
