Detailed Description

Transforms Pixel raw data of a given FED to orca digi and vice versa.

FED OUTPUT DATA FORMAT 6/02, d.k. (11/02 updated for 100*150 pixels)

The output is transmitted through a 64 bit S-link connection. The packet format is defined by the CMS RU group to be : 1st packet header, 64 bits, includes a 6 bit FED id. 2nd packet header, 64 bits. .......................... (detector data) packet trailer, 64 bits. of the 64 bit pixel data records consists of 2 32 bit words. Each 32 bit word includes data from 1 pixel, the bit fields are the following:

6 bit link ID (max 36) - this defines the input link within 1 FED. 5 bit ROC ID (max 24) - this defines the readout chip within one link. 5 bit DCOL ID (max 26) - this defines the double column index with 1 chip. 8 bit pixel ID (max 180) - this defines the pixel address within 1 DCOL. 8 bit ADC vales - this has the charge amplitude.

So, 1 pixel occupies 4 bytes. If the number of pixels is odd, one extra 32 bit word is added (value 0) to fill all 64 bits.

The PixelDataFormatter interpret/format ONLY detector data words (not FED headers or trailer, which are treated elsewhere).
