TMXF336251BL31 Price This bit controls the power state ofthe AC-Iink in AC'97. "0": Normal (default) "1": Power down b13..............PR5: AC'97 Power down Control 5 Setting this bit to "1" disables the internal clock ofAC'97. In case AC'97 is used with DS-1, the master clock is supplied from DS-1. Therefore, when the clock ofAC'97 is stopped completely, set both PR5 and PSN bits to "1". "0": Normal (default) "1": Disable b[15:14] ......AC'97 Power down Control 6 and 7 These bits control PR6 and PR7 status ofthe power control register in AC'97. TMXF336251BL31 on stock The VCA2618 is a highly integrated, dual receive channel, Variable Gain Amplifier (VGA) with analog gain control. The VCA2618's VGA section consists of two parts: the Volt- age Controlled Attenuator (VCA) and the Programmable Gain Amplifier (PGA). The gain and gain range of the PGA can be digitally programmed. The combination of these two program- mable elements results in a variable gain ranging from OdB up to a maximum gain as defined by the user through external connections. The single-ended unity gain input buffer provides predictable high input impedance. The output of the VGA can be used in either a single-ended or differential mode to drive high-performance Analog-to-Digital (ND) converters. A sepa- rate power-down pin reduces power consumption. The VCA2618 also features low crosstalk and outstanding distortion performance. The combination of low noise and gain range programmability make the VCA2618 a versa- tile building block in a number of applications where noise performance is critical. The VCA2618 is available in a TQFP-32 package. SPECIFICATIONS (AD SP-2104/AD SP-2109) Recommended Operating Conditions . . . . . . . Electrical Characteristics . . . . Supply Current & Power . . . .
