TA8552AFN

TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8552AFN TA8552AFN PLL Data Synchronizer For DAT Streamer The TA8552AFN is PLL data synchronizer for digital audio tape (DAT) strteamer, digital data storage (DDS). Features · The TA8552AFN incorporates edge detector, data synchronizer, and latch for data separator. Also the TA8552AFN is available to correspond to ×1, ×2 and ×3 of data transfer rates by adjusting external devices. · The data synchronizer is avalable to correspond to ±7% variation of data transfer rate. Weight: 0.17g (typ.) · By employing full differential signal processing in PLL loop, the TA8552AFN eliminates the influence of external noise. Fast & stable locking is realized by switching between the frequency detective mode and the phase detective mode. · Operating power supply voltage range: 4.5V to 5.5V Pin Connectoion Top view · Small package; SSOP30−P−300−0.65 NC 1 30 RVCO1 2 29 Handle with care to prevent devices from deterioration by static electricity.
