They offer a −3 dB signal bandwidth greater than 750 MHz and channel switch times of less than 20 ns with 1% settling. The ADV3226/ADV3227 include 16 independent output buffers that can be placed into a high impedance state for paralleling crosspoint outputs to prevent off channels from loading the output bus. The ADV3226 has a gain of +1 and the ADV3227 has a gain of +2. They both operate on voltage supplies of ±5 V FUNCTIONAL BLOCK DIAGRAM SER/PAR D0 D1 D2 D3 ADV3226/ ADV3227 80 80 256 80-BIT SHIFT REGISTER WITH 5-BIT PARALLEL LOADING PARALLEL LATCH DECODE 16 × 5:16 DECODERS 16 CLK DATAIN UPDATE CE RESET A0 DATAOUT A1 A2 D4 A3 SWITCH MATRIX SET INDIVIDUAL OR RESET ALL OUTPUTS TO OFF OUTPUT BUFFER G = +1, G = +2 Figure 1. while consuming only 118 mA (ADV3226) and 133 mA (ADV3227) of idle current. Channel switching is performed via a serial digital control that can accommodate daisy chaining of several devices or via a parallel control to allow updating of an individual output without reprogramming the entire array. The ADV3226/ADV3227 are available in the 100-lead LFCSP package over the extended industrial temperature range of −40°C to +85°C. |
