Preliminary specification
30 Mbit/s to 3.2 Gbit/s A-rate
4-bit fibre optic transceiver
TZA3015HW
TXSC(Q). These maximum settings yield the following maximum specification values: I
CCD
= 680 mA,
I
CC(tot)
= 774 mA and P
tot
= 2.7 W.
The output swing is adjustable between 70 mV (typical) and 1100 mV (typical) in 16 steps controlled by bits RFS[3:0]
of the register TXRFOUTC0 (F4h).
The RF input is protected against a differential overvoltage; the maximum input current is 30 mA.
The slice level is adjustable in 256 steps controlled by register LIMSL (D2h).
Guaranteed by design.
The hysteresis is adjustable in 8 steps controlled by bits HTLCB[2:0] of register LIMLOSCON (D1h).
Reference frequency of 19.44 MHz, with a phase-noise of less than
140 dBc for frequencies of more than 12 kHz
from the carrier (measured during 60 seconds, within the appropriate bandwidth).
For bit rates lower than 1.8 Gbit/s, the jitter decreases by the octave division ratio M.
