Functional descriptions • Pixel Array: • Pitch = f (power consumption, radiation hardness), ref. presentation 06/06 • Integration time= f (Nrow) • Different pitches for the 2 layers? • Rectangular pixels? • Matrix steering logic (width ~300 µm) • Placed on the left hand side of the matrix • Rolling shutter binary readout over 5 MHz • Require ~200 ns /row (line of 2 cm long to drive ) • Integration time = 200 ns x Nrow < = 200 µs • Zero suppression: based on SUZE01 architecture, Ref Guy's talk • Time for data reduction treatment = 1 row pixels readout time • Bias reference DAC + JTAG controller • An common reference clock 10 MHz per ladder • Internal CKgenerated viaPLL on chip • Testabilities: like M22, Ref Gilles's talk Ultimate-MimoStar christine.hu@ires.in2p3.fr
Star Ultimate Chip • Zero suppression: physics condition : 2,4 x 105 hits/s/cm2 • Readout time 200 µs ~ 200 hits/frame/sensor with safety factor of 2 (?), ~ 500 hits/frame/sensor • SUZE design: • Maximum output speed: ~100 Mbits/s • 2 memories of (200 x 3) x 32 bits • With new condition & with ~ 10-4 ~ 100 noisy pixels • Zero suppression based on SUZE's group & row hits finders design • Points have to be changed: • Increase maximum output speed: up to 256 Mbits/s • Increase dimension of memory: 3 times larger • Memory: anti latch up?
