Harald Welte 81fc18a0a0 eksos-rj45-breakout-for_slot: Move IDC connectors 11mm towards edge 
It turns out that it's not very easy to bend the 64pos ribbon cable,
so let's make sure the IDC connectors align with  the plane of the
ribbon cable from the PSTN/ISDN line cards.

Harald Welte e12766070d RJ45 breakout board for NOKA EKSOS ISDN / POTS ports 
These board designs  assumes that you use a 64pos (type 3 a+c)
DIN-connector with a flat ribbon cable to a 2x32 2.54mm pitch (IDE/SCSI
style) header to interconnect them.

The point is that assembling that ribbon cable with IDC technology is
much faster than performing soldering or LSA+ type termination on 32
individual wires.

Harald Welte fbae9bd476 plutosdr-revb-extclk: Fix capacitor footprints 
* Always use _0603 and not 0603 (oversized)
* 1uF can be 0603, only 10uF should be 0805

Harald Welte dbd53d6df5 plutosdr-revb-extclk: don't shut-down LTC via SD1/SD2 
In the original PlutoSDR RevC or higher, there's a BSS138 FET
that [optionally] pulls low the SD1/SD2 pins in order to activate
the external clock input.

In this circuit, we don't have GPIO control but permanently enable
the LTC.

Harald Welte 0e6eb31ec7 New design: plutosdr-revb-extclk 
This is a small circuit board containing the "external clock ref input"
circuitry that was added to PlutoSDR RevD.  It can be used to
upgrade/rework RevB boards with the same clock input as the later RevD.

Harald Welte b625dbf06b rj45_jumper_box: Use different RJ45 jack; both on top layer 
The original design (one RJ45 on top, one on bottom) was easy to route
but was difficult to handle. Let's swap both connectors to top, and use
a low-cost Chinese RJ45.
