1. FSAV330
Low On Resistance Quad SPDT Wide Bandwidth Video Switch

2. FLI8125
The FLI8125 is a cost-effective, highly-integrated, mixed signal solution for TV and Digital
Video applications. It incorporates a multi-standard video decoder, high-speed triple 8-bit
Analog-to-Digital Converter(ADC),and front end switching. An integrated VBI Slicer adds
Closed Captioning(CC) and Teletext service support, and the built-in microprocessor enables
full system control without external devices.

O 256K x8 PROM Address. These pins also have bootstrap functionality.
For serial SPI ROM interface:
- ROM_ADDR17 will be Serial Clock (ROM_SCLK)
- ROM_ADDR16 will be Serial Data Output (ROM_SDO)
For 512K X 8 PROM, Address Signal A18 is available thru Pin # 44 which is GPIO10.
