GENERAL DESCRIPTION

The ADV3202/ADV3203 are 32 × 16 analog crosspoint switch matrices. They feature a selectable sync-tip clamp input for ac-coupled applications and a 2:1 on-screen display (OSD) insertion mux. With −48 dB of crosstalk and −80 dB isolation at 5 MHz, the ADV3202/ADV3203 are useful in many high density routing applications. The 0.1 dB flatness out to 60 MHz makes the ADV3202/ADV3203 ideal for both composite and component video switching.
The 16 independent output buffers of the ADV3202/ADV3203 can be placed into a high impedance state for paralleling cross­point outputs so that off-channels present minimal loading to

an output bus if building a larger array. The ADV3202 has a gain of +1 while the ADV3203 has a gain of +2 for ease of use in back-terminated load applications. A single +5 V supply, dual ±2.5 V supplies, or dual ±3.3 V supplies (G = +2) can be used while consuming only 195 mA of idle current with all outputs enabled. The channel switching is performed via a double buffered, serial digital control that can accommodate daisy chaining of several devices.
The ADV3202/ADV3203 are packaged in a 176-lead exposed pad LQFP package (24 mm× 24 mm) and are available over the extended industrial temperature range of −40°C to +85°C.

POWER DISSIPATION

The ADV3202/ADV3203 are operated with ±2.5 V, +5 V, or ±3.3 V supplies and can drive loads down to 150 , resulting in a large range of possible power dissipations. For this reason, extra care must be taken while derating the operating conditions based on ambient temperature.
Packaged in a 176-lead exposed-pad LQFP, the ADV3202/ ADV3203 junction-to-ambient thermal impedance (θ 16°C/W. For long-term reliability, the maximum allowed junction temperature of the die should not exceed 150°C. Temporarily exceeding this limit may cause a shift in parametric performance due to a change in stresses exerted on the die by the package. Exceeding a junction temperature of 175°C for an extended period can result in device failure. Figure 3 shows the range of allowed internal die power dissipations that meet these conditions over the −40°C to +85°C ambient temperature range. When using Figure 3, do not include external load power in the maximum power calculation, but do include load current dropped on the die output transistors.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

THEORY OF OPERATION

The ADV3202/ADV3203 are single-ended crosspoint arrays with 16 outputs, each of which can be connected to any one of 32 inputs.The 32 switchable input stages are connected to each output buffer to form 32-to-1 multiplexers. There are 16 of these multiplexers, each with its inputs wired in parallel, for a total array of 512 stages forming a multicast-capable crosspoint switch. In addition to connecting to any of the nominal inputs (INxx), each output can also be connected to an associated OSD input through an additional 2-to-1 multiplexer at each output. This 2-to-1 multiplexer switches between the output of the 32­to-1 multiplexer and the OSD input.

Decoding logic for each output selects one (or none) of the input stages to drive the output stage. The enabled input stage drives the output stage, which is configured as a unity-gain amplifier in the ADV3202 (see Figure 19). In the ADV3203, an internal resistive feedback network and reference buffer provide for a total output stage gain of +2 (see Figure 20). The input voltage to the reference buffer is the VREF pin. This voltage is common for the entire chip and needs to be driven with a low impedance to avoid crosstalk.

Each input to the ADV3202/ADV3203 is buffered by a receiver. The purpose of this receiver is to provide overvoltage protection for the input stages by limiting signal swing. In the ADV3202, the output of the receiver is limited to ±1.2 V about VREF, while in the ADV3203, the signal swing is limited to ±1.2 V about midsupply. This receiver is configured as a voltage feedback unity-gain amplifier. Excess loop gain bandwidth product reduces the effect of the closed-loop gain on the bandwidth of the device. In addition to a receiver, each input also has a sync-tip clamp for use in ac-coupled applications. This clamp is either enabled or disabled according to the 193
rd
serial data bit. When enabled, the clamp forces the lowest video voltage to the voltage on the VCLAMP pin. The VCLAMP pin is common for the entire chip and needs to be driven with a low impedance to avoid crosstalk.

The output stage of the ADV3202/ADV3203 is designed for low differential gain and phase error when driving composite video signals. It also provides slew current for fast pulse response when driving component video signals.
The outputs of the ADV3202/ADV3203 can be disabled to minimize on-chip power dissipation. When disabled, a series of internal amplifiers drive internal nodes such that a wideband high impedance is presented at the disabled output, even while the output bus is under large signal swings. (In the ADV3203, there is 4 k of resistance terminated to the VREF voltage by the reference buffer). This high impedance allows multiple ICs to be bussed together without additional buffering. Care must be taken to reduce output capacitance, which results in more overshoot and frequency domain peaking. In addition, when the outputs are disabled and driven externally, the voltage applied to them should not exceed the valid output swing range for the ADV3202/ADV3203 to keep these internal amplifiers in their linear range of operation. Applying excess voltage to the disabled outputs can cause damage to the ADV3202/ADV3203 and should be avoided (see the Absolute Maximum Ratings section for guidelines).

ADV3202/ADV3203
The internal connection of the ADV3202/ADV3203 is controlled by a TTL-compatible logic interface. Serial loading into a first rank of latches preprograms each output. A global update signal moves the programming data into the second rank of latches, simultaneously updating all outputs. A serial out pin allows devices to be daisy chained together for single pin programming of multiple ICs. A power-on reset pin is available to prevent bus conflicts by disabling all outputs.
The ADV3202 can operate on a single +5 V supply, powering both the signal path (with the VPOS/VNEG supply pins) and the control logic interface (with the VDD/DGND supply pins). However, to easily interface to ground referenced video signals, split supply operation is possible with ±2.5 V. (The ADV3203 is intended to operate on ±3.3 V.) In the case of split supplies, a flexible logic interface allows the control logic supplies (VDD/DGND) to be run off +3.3 V/0 V to +5 V/0 V while the core remains on split supplies.

APPLICATIONS INFORMATION

PROGRAMMING

The ADV3202/ADV3203 are programmed serially through a 193-bit serial word that updates the matrix and the state of the sync-tip clamps each time the part is programmed.

Serial Programming Description

The serial programming mode uses the CLK, DATA IN, UPDATE
on signal should be high during the time that data is shifted into the serial port of the device. Although the data still shifts in when allow the shifting data to reach the matrix. This causes the matrix to try to update to every intermediate state as defined by the shifting data.
The data at DATA IN is clocked in at every rising edge of CLK. A total of 193 bits must be shifted in to complete the program­ming. For each of the 16 outputs, there are five bits (D0 to D4) that determine the source of its input followed by one bit (D5) that determines the enabled state of the output. If D5 is low (output disabled), the five associated bits (D0 to D4) do not matter because no input is switched to that output. These comprise the first 96 bits of DATA IN. The remaining 96 bits of DATA IN should be set to zero. If a string of 96 zeros is not suffixed to the first 96 bits of DATA IN, a certain test mode is employed that can cause the device to draw up to 30% more current. The last bit, Bit 193, is used to enable or disable the sync-tip clamps. If Bit 193 is low, the sync-tip clamps are disabled; otherwise, they are enabled.
The sync-tip clamp bit is shifted in first, followed by the most significant output address data (OUT15). The enable bit (D5) is shifted in first, followed by the input address (D4 to D0) entered sequentially with D4 first and D0 last. Each remaining output is programmed sequentially, until the least significant output address data is shifted in. At this point, low, which causes the programming of the device according to

Therefore, the data for the last device in the chain should come at the beginning of the programming sequence.
