11 / 82 page  XRT83L34 QUAD T1/E1/J1 LH/SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER ATTENUATOR REV. P1.3.4 PRELIMINARY 8 TCLK_0 TCLK_1 TCLK_2 TCLK_3 1 128 103 102 I Transmitter Clock Input for Channel _0 - Host mode and Hardware mode E1 rate at 2.048MHz ± 50ppm. T1 rate at 1.544MHz ± 32ppm. During normal operation TCLK_0 is used for sampling input data at TPOS_0/ TDATA_0 and TNEG_0/CODES_0 while MCLK is used as the timing refer- ence for the transmit pulse shaping circuit. Transmitter Clock Input for Channel _1 Transmitter Clock Input for Channel _2 Transmitter Clock Input for Channel _3 NOTE: Internally pulled “Low” with a 50k Ω resistor for all channels. TAOS_0 TAOS_1 TAOS_2 TAOS_3 WR_R/W RD_DS ALE_AS CS 69 70 71 72 69 70 71 72 I Transmit All Ones for Channel _0 - Hardware mode Setting this pin "High" enables the transmission of an “All Ones” Pattern from Channel _0. A "Low" level stops the transmission of the “All Ones” Pattern. Transmit All Ones for Channel _1 Transmit All Ones for Channel _2 Transmit All Ones for Channel _3 Host mode: these pins act as various microprocessor functions. See “Micro- processor Interface” on page 9. NOTE: These pins are internally pulled “Low” with a 50k Ω resistor. TXON_0 TXON_1 TXON_2 TXON_3 122 123 124 125 I Transmitter Turn On for Channel _0 Hardware mode Setting this pin "High" turns on the Transmit Section of Channel _0 and has no control of the Channel_0 receiver. When TXON_0 = “0” then TTIP_0 and TRING_0 driver outputs will be tri-stated. NOTE: In Hardware mode only, all receiver channels will be turned on upon power-up and there is no provision to power them off. The receive channels can only be independently powered on or off in Host mode. In Host mode The TXON_n bits in the channel control registers turn each channel Transmit section ON or OFF. However, control of the on/off function can be transferred to the Hardware pins by setting the TXONCTL bit (bit 6) to “1” in the register at address hex 0x42. Transmitter Turn On for Channel _1 Transmitter Turn On for Channel _2 Transmitter Turn On for Channel _3 NOTE: Internally pulled "Low" with a 50k Ω resistor for all channels.
