EQCO30T5.2
1.0 DEVICE OVERVIEW
The EQCO30T5 is a dual slew rate cable driver designed
to drive digital signals over coaxial cable. The EQCO30T5
chip is optimized for driving SMPTE HD-SDI signals, but
works equally well with 8B/10B coded signals.
The EQCO30R5 is a video equalizer that matches to
the EQCO30T5, since it can transmit the uplink signal.
Implementing the uplink requires very few additional
components on both sides of the link, and complies
with SMPTE specifications. The EQCO30R5 data
sheet is available separately from Microchip.
Figure 1-1 shows a typical communication link using
the EQCO30T5 and EQCO30R5 chips:
