AB/RF OPTICAL LINKS [Analog solution] § Analog Modules o Transmitter module: RF_Tx_A (EDA-01331) o Receiver module: RF_Rx_A (EDA-01332) § 6 U 4 TE VME (VME 64 x and VME 64 compatible) o 3 internal registers • Power warning led threshold (RW) • CH/2 1 Power monitoring (Read Only) § Miteq links 3 GHz o validated - Specs: • Measured Phase Noise: – 400 MHz -> 0. 4 ps (pkpk) – 40 MHz -> 0. 4 ps (pkpk) – 10 MHz -> 13 ps (pkpk) More results in the evaluation report • Typical output levels: – Bunch Clock = 0 d. Bm continuous sinewave – Orbit = 1 Vpk pulse on 50 Ohms • Quantities: – 10 links have been ordered in November 05 – 10 to be ordered soon => Enough to work until 2007 Sophie BARON, PH-ESS LEADE, 15/06/06 5

AB/RF OPTICAL LINKS [Analog solution] 150 € 3200 € Sophie BARON, PH-ESS 150 € 2000 € 3200 € LEADE, 15/06/06 2000 € 6

RECEIVER CRATE [Digital Solution] § We tried to find a cheaper solution with the same form factor § Digital Modules (RF_Tx_D and RF_Rx_D) o First test boards made with PHOTON 155 Mbps/TRR-1 B 43 pair • • Standard modules of the TTC modules Performance evaluated on the same setup than the analog links Results available in the test report AB/RF agreed that this could be a cheaper solution for 70% of the links, including the TTC • If the final results are as good as expected, they will use this solution for these 70% and maintain the boards the same way. o Optical components identified and ordered • Photon getting obsolete • OCP components pin compatible components • Price: – Orbit, 10 MHz, 40 MHz: 156 Mbps links – 400 MHz: 1. 2 Gbps o Design on-going (PH/ESS). Tx Rx 156 Mbps PHOTON 197 97 156 Mbps AMS 313 227 1. 2 Gbps AMS 635 295 • Close to the analog boards, but higher density. Sophie BARON, PH-ESS LEADE, 15/06/06 7
