SAF7115

The SAF7115 is designed as one kind of video capture device that incorporates provisions for capturing the serially coded data in the Vertical Blanking Interval (VBI-data) of several standards in parallel. And this device is a combination of a two channel analog preprocessing circuit and a high performance scaler.

Features of the SAF7115 are:(1)Two differential (bi-phase) video inputs as an alternative; (2)Two built-in analog anti-alias filters; (3)Two improved 9-bit CMOS ADCs in differential CMOS style at two-fold ITU-656 oversampling (27 MHz); (4)Fully programmable static gain or Automatic Gain Control (AGC) for the selected CVBS or Y/C channel; (5)Automatic Clamp Control (ACC) for CVBS, Y and C; (6)Switchable white peak control. Two 9-bit video CMOS ADCs, digitized CVBS or Y/C; (7)Signals are available on the expansion port (X-port); (8)Requires only one crystal (32.11 MHz or 24.576 MHz) for all standards; (9)Independent gain and offset adjustments for raw data path; (10)Automatic detection of 50 Hz and 60 Hz field frequencies; (11)Automatic recognition of all common broadcast standards; (12)Enhanced horizontal and vertical sync detection.etc.

The absolute maximum ratings of the SAF7115 can be summarized as:(1)analog supply voltage: -0.5 to +4.6 V;(2)crystal analog supply voltage: -0.5 to +4.6 V;(3)core digital supply voltage: -0.5 to +4.6 V;(4)I/O digital supply voltage: -0.5 to +4.6 V;(5)analog input voltage: -0.5 to +4.6 V;(6)ambient temperature: -40 to +85 °C;(7)storage temperature: -65 to +150 °C;(8)ground supply voltage difference: 100 mV.
