PLL1706

PLL1705 PLL1706 SLES046A – AUGUST 2002 – REVISED SEPTEMBER 2002 3.3-V DUAL PLL MULTICLOCK GENERATOR FEATURES D 27-MHz Master Clock Input D Generated Audio System Clock: www.DataSheet4U.com – SCKO0: 768 fS (fS = 44.1 kHz) – SCKO1: 384 fS, 768 fS (fS = 44.1 kHz) – SCKO2: 256 fS (fS = 32, 44.1, 48, 64, 88.2, 96 kHz) – SCKO3: 384 fS (fS = 32, 44.1, 48, 64, 88.2, 96 kHz) APPLICATIONS D DVD Players D DVD Add-On Cards for Multimedia PCs D Digital HDTV Systems D Set-Top Boxes DESCRIPTION The PLL1705† and PLL1706† are low cost, phase-locked loop (PLL) multiclock generators. The PLL1705 and PLL1706 can generate four system clocks from a 27-MHz reference input frequency. The clock outputs of the PLL1705 can be controlled by sampling frequency-control pins and those of the PLL1706 can be controlled through serial-mode control pins. The device gives customers both cost and space savings by eliminating external components and enables customers to achieve the very low-jitter performance needed for high performance audio DACs and/or ADCs. The PLL1705 and PLL1706 are ideal for MPEG-2 applications which use a 27-MHz master clock such as DVD players, DVD add-on cards for multimedia PCs, digital HDTV systems, and set-top boxes.
