data sheet VT2021 high definition audio codec 9 7 high definition audio link protocol 7.1 link signaling the link protocol defines th e digital serial interface that connects the high definition audio codec to the audio controller, and is not compatible with the previous ac97 protocol. the link is controller synchronous, based on a fixed 24 mhz bitclk and is purely isochronous without any flow control. figure 3 ? high definition audio link conceptual view 7.2 signal definitions table 3 ? high definition au dio link signal description signal name source type description bitclk controller i 24 mhz clock sync controller i global 48 khz fr ame sync and outbound tag signal. sdo controller i bussed serial data output from controller. sdi codec & controller io point-to-point serial data. the controller has a weak pull down. resetn controller i global active low reset signal. bitclk is the 24-mhz clock sourced from the controll er and connecting to all codec on the link. sync marks input and output frame boundaries (frame sync) as well as identifying outbound data streams (stream tags). sync is always sourced from th e controller and connects to all codec on the link. sdo is driven by the controller to all codec on the li nk. compared with ac97, the sdo is double pumped with respect to both rising and falling edges of bitclk in order to increase the bandwidth required for high definition audio link. sdi is a point-to-point data signal driven by th e codec to the controller. because the bandwidth requirement is not that high compared with sdo, the data is single pumped with respect to only the rising edge of bitclk. the controller is required to implement weak pull-down on all sdi signals. resetn is sourced from the controller and connects to all codec on the link. assertion of resetn results in all link interface logic being reset to default power on state. free datasheet http://www.0pdf.com
data sheet VT2021 high definition audio codec 10 the following figure shows the timing diagram of bitclk, sync, sdo and sdi. figure 4 ? bit timing diagram figure 5 ? sync and sdo timing relative to bitclk figure 5 shows that both sync and sdo may be toggled with respect to either edge of bitclk. in particular, bit cell n+1 is driven by the controller on sdo with respect to clock edge #2, and is sampled by the codec with respect to the subsequent clock edge, #3, and so forth. figure 6 ? sdi timing relative to bitclk figure 6 shows that sid may only be toggled with respect to the rising edge of bitclk. in particular, bit cell n+1 is driven by the codec on sdi with respec t to rising clock edge #2 and is sampled by the controller with respect to the subsequent rising clock edge, #3, and so forth. free datasheet http://www.0pdf.com

data sheet VT2021 high definition audio codec 12 both inbound and outbound frames are made up of three major components, specifically: y a single command / response field y zero or more stream packets y a null field to fill out the frame figure 9 ? frame composition command / response field is used for link and codec manage ment. one of these fields appears exactly once per frame, msb first, and is always the first field in the frame. it is composed of a 40-bit command field on each outbound fr ame from the controller and a 36-bit response field on each inbound frame from the codec. stream tag is the label at the beginning of each stream packet that provides the associated stream id. all data in one stream packet belongs to a single stream. sample block is a set of one or more samples, the number of which is specified by the ?channels? field of the stream descriptor format registers. samples in a given sample block are associated with a single given stream, have the same sample size, and have the same time reference. and no padding is permitted between samples. ordering of samples within a block is always the same for all blocks in a given stream. sample is a set of bits providing a single sample point of a single analog waveform. null field is used to fill up the remainder of the bits in each frame that are not used for command / response or packets. a null field mu st be transmitted as logical 0?s. free datasheet http://www.0pdf.com
data sheet VT2021 high definition audio codec 13 7.5 output frame 7.5.1 stream tags outbound stream tags are 8 bits in length and are transmitted at a double pu mped rate as side band information on sync. it is composed of a 4-bit prea mble which is signaled as three sdo bit times high followed by one sdo bit time low. this is immediatel y followed by a 4-bit stream id. outbound stream tags are transmitted on sync so as to align with the last eight data bits of th e preceding stream packet or command field. figure 10 ? outbound stream tag format and transmission 7.5.2 outbound frames outbound frames start and end between the falling edge s of successive frame syncs. the first 40 bits are dedicated for the command field and are sued to send commands to codec. the controller transmits the tag for the first outbound packet on sync during the last eight bit times of the command field. the sample blocks for the first packet are transmitted on sdo immediately following the command field. there is no proscribed order in wh ich the different stream packets are to be transmitted. the controllers are required to transmit a null field for the re maining bits within an outbound frame when the transmission of the stream packets co mpletes before the end of the frame. figure 11 ? outbound frame with null field free datasheet http://www.0pdf.com
data sheet VT2021 high definition audio codec 14 7.6 input frame 7.6.1 stream tags an inbound stream tag is 10 bits in length, and is transmitted ?in-line? at a single pumped rate on sdi, immediately preceding the associated inbound sample blocks. it is composed of a 4-bit stream id, followed by a 6-bit data length field that provides the length, in bytes, of all sample blocks with the given stream packet. figure 12 ? inbound tag fo rmat and transmission 7.6.2 inbound frames inbound frames start and end between the falling edge s of successive frame syncs. the first 36 bits of an inbound frame are dedicated for the response field, which codec use for sending responses to controller commands. the codec transmits the first stream packet on sid immediately following the response field. a stream tag indicating a packet leng th of zero must immediat ely follow the last stream packet to be transmitted. such a stream tag marks the completion of data transmission within that frame, and the remaining valid bit positions are set to the null field. in the event there are less than 10 valid bit positions remaining in the frame after the last stream packet, then no termination tag is transmitted, and the remaining bits are the null field. figure 13 ? inbound frame with no null field free datasheet http://www.0pdf.com
data sheet VT2021 high definition audio codec 15 7.7 reset and initialization 7.7.1 link reset a link reset is signaled on the link by assertion of the resetn signal, and results in all link interface logic in both codec and controller, includ ing registers, being initialized to their default state. the controller drives all sdo and sync outputs low when entering or exiting link reset. a controller may only initiate the link reset entr y sequence after completi ng any currently pending initialization or state change requests. figure 14 ? link reset entry sequence the sequence when entering link reset is described as the following. 1. the controller synchronously completes the current frame but does not signal frame sync during the last eight sdo bit times. 2. the controller synchronously asserts resetn four or more bitclk cycles after the completion of the current frame. 3. bitclk is stopped a minimum of four clocks after the assertion of resetn. in the event of a host bus reset, the above sequence does not complete, and resetn is asynchronously asserted immediately and unconditionally. regardless of the reason for entering link reset, it may be exited on ly under software control and in a synchronous manner. figure 15 ? link reset exit sequence free datasheet http://www.0pdf.com
data sheet VT2021 high definition audio codec 16 the sequence when exiting link reset is described in the following. 1. the controller provides a properly running bitclk for a minimum of 100 s (2400 bitclk cycles or more) before the de-assertion of resetn. this allows time for codec plls to lock. 2. the resetn signal is de-asserted. 3. the sync commences signaling valid frames on the link with the first frame sync that occurs at a minimum of four bitclk cycles after the de-assertion of resetn. 4. the codec must signal an initialization request via sid within the first 25 frame syncs relative to the de-assertion of thei r respective resetn signal. 7.7.2 codec function group reset a codec function group reset is initiated via the function_reset verb and results in all logic within the targeted function group being driven to its default or reset state. by default VT2021 does not signal a state change and initialization request on sdi after the function_reset verb, and still keeps its codec address previously assigned by the controller. this behavior can be changed by setting a vendor defined register bit for backward compatible with the high definition audio spec. see the vendor defined verbs in the audio function group for the detail. 7.7.3 codec initialization immediately following the completion of link reset sequence (or function_reset verb, if enabled by the vendor-defined verb), VT2021 proceeds through a codec initialization sequence, which provides each codec with a unique address by which it can therea fter be referenced to commands on the sdo signal. during this sequence, the controller provides each requesting codec with a unique address using its attached sdi signals. figure 16 ? codec initialization sequence the codec initialization sequence occurs across three contiguous frames immediately following any reset sequence. during these three frames, the codec are re quired to ignore all outbound traffic present on sync & sdo. these three frames, labeled as the ?connect frame?, the ?turnaround frame?, and the ?address frame?, are described in the following sub-section. free datasheet http://www.0pdf.com
data sheet VT2021 high definition audio codec 17 7.7.3.1 connect and turnaround frames in the connect and turnaround frames, the codec sign als its request for initialization on sdi and then releases sdi (turnaround) to be driven by the controller in the subsequent address frame. figure 17 ? connect and turnaround frames the codec signals an initialization re quest by synchronously driving sdi hi gh during last bit clock cycle of frame sync. sdi must be asserted for the entire bi tclk cycle and must be synchronously de-asserted the same rising edge of bitclk as the de-assertion of the frame sync. the codec are only permitted to signal an initialization request on a null input frame, a frame in wh ich no response stream or input streams are being sent. in the turnaround frame, the codec and controllers ar e required to turn sdi around upon the completion of the connect frame. to do this, the codec active ly drives sdi low for one bitclk cycle immediately following the de-assertion of sync at the end of th e connect frame. the codec then puts its sdi drivers in a high impedance state at the end of the first bitclk cycle in the turnaround frame. four bitclk cycles before the end of the turnaround frame, sync and sid are driven high by the controller. the sdi remains driven high through the end of the turnaro und frame in preparation for the subsequent address frame. free datasheet http://www.0pdf.com
data sheet VT2021 high definition audio codec 18 7.7.3.2 address frames during the address frame, sdi is a codec input and is driven by the controller beginning in the last four bitclk periods (frame sync) of the turnaround fram e. the falling edge of frame sync marks the start of codec address assignment. address assignment is in dicated by the controller holding each sdi high for the number of bitclk cycles equal to the numeric id of that particular sdi. thus the unique address of the codec becomes the id of its attached sdi. figure 18 ? address frame the codec count from zero to fourteen starting on the rising edge of bitckl following the de-assertion of frame sync, and sample the value of this count for thei r unique address on the first rising edge of bitclk in which sync and sdi are both sampled low. the controller must put its sdi drivers in a high impedance state by the rising edge of the 18 th bitclk of the address frame but not before driving each sdi low for at least one clock cycle. the sdi then becomes an input to the controller. normal link operation starts on the frame following the completion of the address frame, and the codec is required to actively dr ive a valid response field and to be ready to accept commands in this an d subsequent frames. free datasheet http://www.0pdf.com
