SM5307C

SM5307C 3-channel Video Buffer OVERVIEW The SM5307C is a 3-channel video buffer for the HD output equipment that corresponds to the 480i to 1080p video signal standards. It can change the 5th-order lowpass filter (LPF) which is mounted on this IC, to four modes of SD1, SD2, HD and filter-bypass mode, which corresponds to video signal. In addition, improvement of S/N characteristic with HD band is actualized. FEATURES I Supply voltages: 4.75 to 5.25V I Current consumption Normal operation: 65mA (typ, VCC = 5.0V) Disable mode: 1.8mA (typ, VCC = 5.0V) I Output gain: 6.0dB ± 0.5dB I LPF passband SD1 mode CH1, CH2, CH3 = 6.75MHz SD2 mode CH1, CH2, CH3 = 13.5MHz HD mode CH1, CH2, CH3 = 30MHz I Filter-bypass mode corresponding to 1080p: 80MHz (typ) I Maximum input amplitude: 1.4Vp-p I S/N ratio: 70dB (typ) I Input multiplexer: 2-system input, 1-system output I Input type: Bias (CH1, CH2, CH3) I Disable mode function (power-down mode) I Operating ambient temperature range: −40 to 85°C I Package: 24-pin VSOP (Pb free) APPLICATIONS I DVD player I DVD recorder I Set Top Box PINOUT (Top view) FC1 IN1A IN1B VCC NC IN2A IN2B NC GND IN3A IN3B DISABLE 1 12 24 FC2 NC GND NC OUT1 VCC OUT2 GND OUT3 NC VCC 13 MUXSEL PACKAGE DIMENSIONS (Unit: mm) 7.9 ± 0.2 0.15 + − 0.1 0.05 ORDERING INFORMATION 0.5 ± 0.2 Device SM5307CV Package 24-pin VSOP 0 to 10 5.6 ± 0.2 7.6 ± 0.2 1.15 ± 0.1 0.65 0.10 + 0.1 0.22 − 0.05 0.12 M 0.10 ± 0.05 SEIKO NPC CORPORATION —1 BLOCK DIAGRAM SM530...
