MULTI-CLOCK GENERATOR
FEATURES
● 27MHZ MASTER CLOCK INPUT
DESCRIPTION
The PLL1700 is a low cost, multi-clock generator
Phase Lock Loop (PLL).
● GENERATED AUDIO SYSTEM CLOCK:
SCKO1: 33.8688MHz (Fixed)
SCKO2: 256fS
The PLL1700 can generate four systems clocks from a
27MHz reference input frequency.
SCKO3: 384fS
SCKO4: 768fS
The device gives customers both cost and space savings
by eliminating external components and enables cus-
tomers to achive the very low jitter performance needed
for high performance audio digital-to-analog convert-
ers (DAC) and/or analog-to-digital converters (ADC).
● ZERO PPM ERROR OUTPUT CLOCKS
● LOW CLOCK JITTER: 150ps at SCKO3
● MULTIPLE SAMPLING FREQUENCIES:
fS = 32kHz, 44.1kHz, 48kHz, 64kHz,
88.2kHz, 96kHz
The PLL1700 is ideal for MPEG-2 applications which
use a 27MHz master clock such as DVD players, DVD
add-on cards for multimedia PCs, digital HDTV sys-
tems, and set-top boxes.
● +3.3V CMOS LOGIC INTERFACE
● DUAL POWER SUPPLIES: +5V and +3.3V
● SMALL PACKAGE: 20-Lead SSOP
