• Manufacturer Part Number: tza3015hw
• Description: 30 Mbit/s To 3.2 Gbit/s A-rate 4-bit Fibre Optic Transceiver
• Manufacturer: NXP Semiconductors

Philips Semiconductors
3. The output swing is adjustable between 70 mV (typical) and 1100 mV (typical) in 16 steps controlled by bits RFS[3:0]
4. The RF input is protected against a differential overvoltage; the maximum input current is 30 mA.
5. The slice level is adjustable in 256 steps controlled by register LIMSL (D2h).
6. Guaranteed by design.
7. The hysteresis is adjustable in 8 steps controlled by bits HTLCB[2:0] of register LIMLOSCON (D1h).
8. Reference frequency of 19.44 MHz, with a phase-noise of less than 140 dBc for frequencies of more than 12 kHz
9. For bit rates lower than 1.8 Gbit/s, the jitter decreases by the octave division ratio M.
