FSAV450 — 800MHz, 4-Channel, 2:1 Video Switch Features Description The FSAV450 is a high performance Quad Sinple-Pole Double-Throw (SPDT) (2-to-1 multiplexer/ demultiplexer) video switch designed specifically for switching high definition YPbPr and computer RGB (up to UXGA) signals. The bandwidth of this device is 800MHz (typical) which allows signals to pass with minimal edge and phase distortion. Image integrity is maintained with low crosstalk, high off-Isolation and low differential gain and phase. The low on resistance (4 typical) minimizes signal insertion loss. Low voltage operation (3V), low power consumption (1µA maximum) and small scale packaging (including leadless DQFN) make this device ideal for a broad range of applications. -50dB Off Isolation at 30MHz -80dB Non-Adjacent Channel Crosstalk at 30MHz 3dB Bandwidth: 800MHz On Resistance: 4 (Typical) Low Power Consumption: 1µA (Maximum) Control Input TTL Compatible Applications RGB Video Switch in LCD, Plasma and Projector Displays Ordering Information Part Number FSAV450BQX Operating Temperature Range Package Packing Method -40 to +85°C 16-Terminal Depopulated Quad Very-Thin Flat Pack No Leads (DQFN), JEDEC MO-241, 2.5 x 3.5mm Tape and Reel Figure 1.
