GX4201-CTA中文资料根努姆数据手册PDF规格书

CIRCUIT DESCRIPTION

The GX4201 is a wideband 1x1 video crosspoint implemented in bipolar monolithic technology. The device is characterized by excellent differential gain and phase in the enabled state, and very high off-isolation in the disabled state. The fully buffered unilateral signal path ensures negligible output to input feedback while delivering minimal output switching transients through make-before-break switching.

FEATURES

• -3 dB bandwidth, 300 MHz with CL = 0 pF

• off isolation at 100 MHz, 80 dB

• differential phase and gain at 4.43 MHz, 0.01° & 0.02

• 800 µW disabled power consumption

• input signal levels from -2 V to +3 V

• logic input compatible with TTL and 5 V CMOS

• open collector TALLY output

APPLICATIONS

• very high quality video switching

• HDTV

• computer graphics

• RF switching/routing

• PCM/data routing
