The TC2411 provides an on-chip temperature diode which may be used to monitor die temperature. Applying
+5V to the anode pin and measuring the cathode node voltage into a 2K ohm load, the user can convert the
resulting voltage into a temperature. Contact TelASIC sales for further information.
VOUT_REF is an internally generated, +2.5V precision bandgap reference. Tie this output to VREF_RA, the
ref amp input.
The TC2411 offers a Standby Mode capability whereby the power dissipation is reduced to 850mW. The
standby function comes in on pins L14 (SLP) and M14 (SLN). Under normal operation both pins are left
floating. This mode may be enabled with either a single-ended drive or a differential drive.
Pins DNC1 (C1), DNC2 (D2), and DNC3 (M13) should be left floating. Connecting these pins to ground or to
either supply voltage will alter device performance and may damage the part.
The on-chip reference amplifier requires an external capacitor to maintain excellent phase noise and jitter
characteristics. Attach two capacitors, 0.01 uF and 1000 pF, in parallel between the EXTCAP pin and -5V
analog supply.
Single-ended drive, M14 (SLN) pin should be left floating and L14 (SLP) pin should be held low at +0.0V for
normal operation, L14 (SLP) pin should be held high at +3.3V (CMOS) for standby mode.
Differential drive level requires external 100 ohm resistor between pins L14 (SLP) and M14 SLN) and uses
standard LVDS, (i.e. low level is 1.0V, high level is 1.4V). For normal mode M14 (SLN) is set low and L14
(SLP) is set high. For sleep mode M14 (SLN) is set high and L14 (SLP) is set low.
