STPCCONSUMER Datasheet The buffered CCD output is capacitively coupled to the VSP2232. The purpose of the input clamp is to restore the dc component of the input signal that was lost with the ac-coupling and establish the desired dc bias point for the CDS. Figure l shows the simplified block diagram of the input clamp. The input level is clamped to the internal reference voltage REFN (1.25 V) during the dummy pixelinterval. More specifically, when both CLPDM and SHP are active, then the dummy clamp function becomes active. If the dummy pixels and/or the CLPDM pulse are not available in yoursystem, the CLPOB pulse can be used in place ofCLPDM as long as the clamping takes place during black pixels. In this case, both CPLDM pin (actives as same timing as CLPOB) and SHP become active during the optical black pixel interval, then the dummy clamp function becomes active. STPCCONSUMER Price Notes: 16. The clocks (RCLK, WCLK) can be free-running during reset. _ 1 7. After reset, the outputs will be LOW if OE = 0 and three-state if OE = 1. 18. When tSKEW2 > minimum specification, tFRL (rTiaxirTiUrTl) = tCLK + tSKEW2 Wheri tSKEW2 < rTiiriicTIUrTi specificatiori, tFRL (maximum) = either 2*tCLK + tSKEW2 or tCLK + tSKEW2 The Latency Timing applies only at the Empty Boundary (EF = LOW). 19. The first word is always available the cycle after EF goes HIGH. STPCCONSUMER on stock The complex 200 Q + 680 Q ll100 nF termination and hybrid balance is digitally synthesized by the T7507 codec. Additionally, the Tip/Ring to PCM (transmit) gain is fixed and set digitally by the T7507 codec at 0 dB.The PCM to Tip/Ring (receive) gain is also digi- tally set by the T7507 codec and is programmable via a bil in the codec serial data control stream to either -3.5 dB or -7.0 dB.
