• Cost and Status of V5 Boards– Boards 3 and 4 were modified to improve the QPLL and

Crystal layout • It was determined that if a change was to be made to the PCB that

there should be redundancy added to the circuitry in the case that a QPLL/Crystal became faulty.

• It was determined that a 2nd QPLL should be added to the circuitry along with a means to change which QPLL/Crystal was responsible for driving the clock to the FE modules via the backplane.

• The logic for making the QPLL selection was built using PECL logic which has shown to be RAD Tolerant.

• The new layout of the QPLL circuitry was done as per Paulo Moreira(QPLL designer) suggestions, along with suggestions from others that have experience using the device.

• Cost and Status of V5 Boards– It was determined that Boards 1 & 5 should also be

produced to alleviate the problem of not having enough CCM’s for test stands and spares.

• The previous version of Board 5 has a number of modifications that were fixed in the V5 boards – a new but very similar layout was done.

• Board 1 did not have any changes made to the logic or layout, how ever new Gerbers were produced that have a V5 and date on the silkscreen.

• Cost of V5 Boards– Board 1

• 25 PCB = $1384 = $55.36 each• Parts = $150 - this is an estimate based on buying all new parts, Fermilab has a stock of parts that are

available and will be assembled onto the 20 boards.• Assembly = $1450 per 20 pcb ($32 each plus NRE)• The remaining 5 boards will be assembled at Fermilab with a labor estimate of 3 days.• Total for 25 boards = $6584 + 3 days

– Board 5 • 25 PCB = $1377 = $55.08 each• Parts = $275 - this is an estimate based on buying all new parts, Fermilab has a stock of parts that are

available and will be assembled onto the 20 boards.• There are two ACTEL FPGA’s on the board which are one time programmable, we have a stock of 17

programmed larger parts, we purchased 60 programmed units of the smaller part at $56.45 each.• Assembly = $1458 per 20 pcb ($32 each plus NRE)• The remaining 5 boards will be assembled at Fermilab with a labor estimate of 4 days.• Total for 25 boards = $9710 + 4 days

• Cost of V5 Boards– Board 3

• 25 PCB = $1370 = $54.80 each• Parts = $100 - this is an estimate based on buying all new parts, Fermilab has a stock of parts that

are available and will be assembled onto the 20 boards.• Assembly = $1305 per 20 pcb ($25 each plus NRE)• The remaining 5 boards have been assembled at Fermilab with a labor cost of 3 days.• Total for 25 boards = $5175 + 3 days

– Board 4 • 25 PCB = $1370 = $54.80 each• Parts = $90 - this is an estimate based on buying all new parts, Fermilab has a stock of parts that

are available and will be assembled onto the 20 boards.• Assembly = $1251 per 20 pcb ($23 each plus NRE)• The remaining 5 boards have been assembled at Fermilab with a labor cost of 3 days.• Total for 25 boards = $4871 + 3 days

• Status of V5 Boards– Board 3 and 4

• 25 boards of each produced• 5 boards assembled of each at Fermilab• 1 each in Test stand Fermilab

• 2 sets of each at CERN• Assembly of the other 20 sets is scheduled for Sept. 18th

– Board 1 and 5 • 25 boards of each produced• 5 boards of each will be assembled at Fermilab when time permits• Assembly of the other 20 sets is scheduled for Sept. 18 th

– CCM Shell • The cost to produce 25 Aluminum Shells for the 25 sets of V5 CCM boards:• Material and Machining = $1000• Time (Maurizio) = $3000
