PLL1707DBQR

The PLL1707DBQR belongs to PLL1707 family which are low cost, phase-locked loop (PLL) multiclock generators and it can generate four system clocks from a 27-MHz reference input frequency. The clock outputs of the PLL1707 can be controlled by sampling frequency-control pins. The PLL1707 is ideal for MPEG-2 applications which use a 27-MHz master clock such as DVD recorders, HDD recorders, DVD add-on cards for multimedia PCs, digital HDTV systems, and set-top boxes. 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 features of PLL1707DBQR can be summarized as (1)27-MHz master clock input; (2)generated audio system clock (PLL1707): SCKO0: 768 fS (fS = 44.1 kHz) SCKO1: 768 fS, 512 fS (fS = 48 kHz) SCKO2: 256 fS (fS = 32, 44.1, 48, 64, 88.2,; (3)96 kHz) SCKO3: 384 fS (fS = 32, 44.1, 48, 64, 88.2, 96 kHz); (4)generated audio system clock (PLL1708): SCKO0: 768 fS (fS = 44.1 kHz) SCKO1: 768 fS, 512 fS, 384 fS, 256 fS (fS = 48 kHz) SCKO2: 256 fS (fS = 16, 22.05, 24, 32, 44.1, 48, 64, 88.2, 96 kHz) SCKO3: 384 fS (fS = 16, 22.05, 24, 32, 44.1, 48, 64, 88.2, 96 kHz); (5)Zero PPM error output clocks; (6)low clock jitter: 50 ps (Typical); (7)multiple sampling frequencies (PLL1707): fS = 32, 44.1, 48, 64, 88.2, 96 kHz; (8)multiple sampling frequencies (PLL1708): fS = 16, 22.05, 24, 32, 44.1, 48, 64, 88.2, 96 kHz; (9)3.3-V single power supply; (10)PLL1707: parallel control PLL1708: Serial Control; (11)package: 20-Pin SSOP (150 mil), Lead-Free Product.
