We are designing a microTCA module called the DTC (DAQ and Timing Card) for the HCAL SLHC readout. It is currently envisioned that this will occupy one of the MCH slots in a dual-star type crate. Initially we would build cards for MCH connectors 1 and 2, providing clock distribution on finger 2, and fast controls and trigger feedback on port 1 of fabric A on finger 1.

Design Thoughts

Clocking – per AMC spec:

Type	AMC Name	μTCA Name	Contacts	Direction
Telecom	TCLKA	CLK1	74/75	In to AMC
Telecom	TCLKB	CLK2	77/78	Out from AMC
Telecom	TCLKC		135/136	In to AMC
Telecom	TCLKD		138/139	Out from AMC
Fabric	FCLKA	CLK3	80/81	In to AMC

On the CTR2 FCLKA, TCLKA and TCLKC all enter an SN65LVDT125A LVDS crosspoint switch, and from there can be routed to the FPGA or links, possibly via an Si5319 frequency synthesizer.

Also, MiniCTR2 connects to ports 0, 1, 8 with GTX. All other ports are connected to generic FPGA I/Os.

Jeremy's requests: Transmit LHC clock on CLK1 or CLK3. TTC encoded stream on Fabric B Tx (port 2/3). TTS received on Fabric B Rx (port 2/3).

CorEdge mini crate backplane: Only CLK2, CLK3 routed. Fabric A to port 0. Fabric B to port 2. Fabrics D-G to ports 4-7.

Wu would prefer to send TTC on a fabric D-G because they are on T3. Instead I think we should send them on fabric B.
