• Manufacturer Part Number: ucb1200
• Description: Advanced Modem/audio Analog Front-end
• Manufacturer: NXP Semiconductors

Philips Semiconductors
Notes
1. I/O
2. V
3. SKPRN/SPKRP (pins 8 and 9), TINN/TINP (pins 14 and 15) and TOUTP/TOUTN are differential pairs
4. TEST (pin 13) is connected to an internal pull-down resistor. This pin should be held LOW during normal operation
5. The not connected pins (pins 6, 19, 31 and 44) are reserved for future applications and should be left floating.
6. SIBDOUT reset state is 1 until the SIB bus is running. SIBDOUT will be active once the SIB bus has started.
