1 / 13 page SM5307A SEIKO NPC CORPORATION —1 3-channel Video Buffer OVERVIEW The SM5307A 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: 1.4mA (typ, VCC = 5.0V) I Output gain: 6.0dB ± 0.5dB I LPF passband • SD1 mode CH1 = 6.75MHz CH2, CH3 = 3.375MHz • SD2 mode CH1 = 13.5MHz CH2, CH3 = 6.75MHz • HD mode CH1 = 30MHz CH2, CH3 = 15MHz 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 • CH1: Synctip clamp • CH2, CH3: Bias 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 ORDERING INFORMATION PINOUT (Top view) PACKAGE DIMENSIONS (Unit: mm) Device Package SM5307AV 24-pin VSOP OUT3 VCC IN3A IN1A FC1 FC2 IN2A OUT1 IN2B GND 1 13 12 IN1B NC GND IN3B DISABLE NC VCC NC OUT2 GND NC NC VCC MUXSEL 24 0 to 10 7.9 ± 0.2 0.65 0.22 − 0.05 + 0.1 0.12 M 0.10 0.15 − 0.05 + 0.1 |
