avpro ? 5001 quad a/v drivers september 1999 description the avpro 5001 device is an audio/video driver ic that supports four video inputs and two audio inputs. each video paths has a gain of 2 with output buffers designed to drive a 137 ohm load. each audio path has two output drivers that are buffered to provide 2 vrms output (3.2 vrms maximum). in addition, the audio drivers use +/- 5 volt power supplies so that the output is centered around ground. this allows direct coupling of the 5001 audio outputs to the associated load. typical applications for the 5001 include dvd players, vcrs, and digital receivers for satellite, cable, and terrestrial television. features video section - internal dc restore circuits - 150 ohm drivers audio section - better than 90 db snr+distortion - direct coupled outputs +5v and -5v power supplies 24-lead small outline (so) package block diagram advanced information vid3 vid4_out vid2 cbyp vid1 aud2 aud1 veev vid1_out vcca gndv aud1_out2 aud1_out1 aud2_out2 aud2_out1 vccv veea mode tgen gnda rref vid2_out osc ref gen vid3_out vid4 dcr dcr dcr dcr
avpro ? 5001 quad a/v drivers 2 video description the 5001 video section provides inputs for four video signals which are typically ac coupled into the device. the pin labeled mode is used to select the type of video inputs that are supported. when the mode pin is connected to ground, the device is configured to support luma (y), chroma (c), and two composite signals. in this mode, the vid1, vid2 , and vid3 paths each have an active dc restore circuit. the dc restore circuit triggers on the falling edge of the incoming video sync pulse and then tries to force the blank level to a fixed dc value. the trigger from the vid1 path is also passed along to the vid2 and vid3 paths to insure that the dc restore circuits are triggered. the vid4 path is used for a chroma signal. this path is set to a fixed dc level of 0.89v. when the mode pin is left open, the device is configured to support rgb signals and a composite signal. in this mode, all video paths have active dc restore circuits. the vid1 path provides a master trigger to the other three dc restore circuits. this accommodates an application where the video sync for the rgb signals is provided by the composite signal. the vid2 path also provides a trigger for the vid3 and vid4 pins. this supports applications where the sync signal is embedded in one of the rgb signals (sync on green). for this application, the video source that contains the sync pulse must be applied to vid2 . an internal timing circuit is used to allow the dc restore circuit to initially acquire the correct dc level. the timing circuit requires that a 470 pf capacitor be connected between the tgen pin and ground. the output amplifiers are designed to provide a gain of approximately two (2) so that a 137 ohm load can be driven. the output impedance of each video driver is nominally 12 ohm. an external 62 ohm resistor is placed in series with the output to provide a nominal 75 ohm output impedance to the system. audio description the 5001 audio section provides inputs for two audio signals, typically left and right channels of a stereo audio source. in many applications, the audio inputs are generated by an external dac. the impedance of the 5001 audio input is approximately 40k ohms. each input has two independently buffered outputs. each buffer can output a signal of 2 vpp. the audio buffers use +5v and -5v power supplies which allow the dc level of the output to be 0 vdc. for most applications, this allows the inputs and outputs of the 5001 to be direct coupled to the source and load. a resistor in series with the load is suggested to provide over-current protection. reference generator the 5001 generates internal reference currents based on an external 10.0k ohm, 1% resistor connected between the rref pin and analog ground. the reference generator also uses a 0.01 uf capacitor connected between the cbyp pin and analog ground for filtering purposes. vid1 vid1_out tgen osc dcr r l = 75 470 pf 62 typical video circuit aud1 aud1_out1 r l = 10k 270 typical audio circuit r l = 10k 270 aud1_out2
